Surface finish is an important element in any specification of stainless steel regardless of the intended use. For those applications where appearance is important, finish is a design element and must be specified. In non-decorative applications the surface finish may have implications for friction, wear, maintenance or corrosion resistance and must, therefore, also be carefully chosen and clearly specified.
Types of Finish
Stainless steel is available in a wide variety of standard and special finishes. The majority of finishes can be divided into three categories:
~Mill finishes
~ Mechanically polished finishes
~ Special finishes
In each case the finishes are described under either their appropriate Standard or the name by which they are commonly known. In some instances a finish may commonly be known by several names, leading to some misunderstandings.
There are a wide range of decorative finishes available; therefore, it is important to pay close attention to the selection of the most appropriate finish for the application required. For highly visible applications the appearance of stainless steel is a critical design element and a misunderstanding of the wrong finish can alter the desired effect. In commercial and hygienic applications, such as restaurants and hospitals, properly finished stainless steel is easier to keep clean. In consumer products, such as catering equipment, the lustre from a well polished sheet of stainless steel has strong sales appeal.
In addition to the visual appearance of polished stainless steel there are a number of functional considerations. In sanitary applications correctly polished stainless steel not only looks good but it helps to reduce the risk of bacteria being retained by the material.
In aggressive environments, such as in the nuclear or offshore industries, a correctly polished stainless steel surface has a better resistance to corrosion than a surface that is roughly or badly polished. A smooth surface is less susceptible to an accumulation of deposits and stainless, which often become focal points for localised corrosion. All stainless steel finishes perform better when cleaned and maintained and details of correct cleaning procedures may be found in our publication, “The Cleaning and Maintenance of Stainless Steel”.
Some fabrication operations, such as grinding prior to painting or gluing, may require a rough surface finish but, generally speaking, a smooth, well finished sheet requires less physical effort than a coarse, rough one when it comes to blending. Certain finishes are more difficult to recreate by hand than others, causing fabrication difficulties; this is especially true of the “special” finishes which cannot be easily replicated in a fabrications workshop.
The surface of stainless steel is actually and extremely thin but stable and passive Chromium rich oxide film, on which Stainless Steel relies for its excellent corrosion resistance. The surface finish on Stainless Steel should therefore be developed and maintained to ensure this vital property, and also for the secondary reason of the pleasing aesthetic appearance of stainless steel.
Standard Mill Finished - Stainless Steel Flat Rolled Products
The Standard Mill Surface Finished are laid down in Specifications BS 1449, Part 4, and the Committee of Stainless Steel Producers, American Iron & Steel Institute.
The finished are designated by a system of numbers, and these are broadly described hereunder relative to the finishing operations employed. It should be remembered that different grades of Stainless Steel can result in a variation of visual appearance for the same finishing operation. The thickness can also have an effect, generally the thinner the material the smoother the surface finish.
The thicker gauge sizes of Stainless Steel are hot rolled. This is done at high temperatures and will always result in a scaled surface. Stainless Steel Flat Product is supplied in the annealed ie fully softened condition.
This is also a high temperature operation and unless carried out in a very closely controlled inert atmosphere, will result in oxidation (scaling) of the surface.
The scale is usually removed by a pickling process, that is the removal of the scale by use of suitable acids, and the passivated by the use of Nitric Acid.
No. 0 Finish HRA
Also referred to as Hot Rolled Annealed (HRA). The plate is hot rolled to required thickness, and then annealed. No pickling or passivation operations are effected, resulting in a scaled black finish.
This does not develop the fully corrosion resistant film on the Stainless Steel, and except for certain high temperature heat resisting applications, this finish is unsuitable for general end uses.
No 1 Finish
Plate is hot rolled, annealed, pickled and passivated. This results in a dull, slightly rough surface; quite suitable for industrial applications which generally involve the range of plate thicknesses. Grinding marks may be visible in isolated areas.
Some of the thinner thicknesses within the plate range are Cold Rolled; but Sheet, Coil and Strip gauge are produced by Cold Rolling, ie rolled without and heating of the material. Cold rolling hardens the material, and the thinner sizes may have to be subjected to an intermediate annealing and pickle, or bright annealed, during the reduction of thickness to final gauge.
The starting material for Cold Rolling always has a No. 1 finish. Cold Rolled material is supplied with the following standard mill finishes.
No 2D Finish
A no. 1 Finish after being Cold Rolled, Annealed, Pickled and Passivated. This results in a uniform dull matt finish, superior to a No. 1 Finish.
Suitable for industrial application, and eminently suitable for severe deep drawing as the dull surface, (which may be polished after fabrication) retains the lubricant during the drawing operation.
No 2B Finish
A 2D Finish is given a subsequent light skin pass cold rolling operation between polished rolls.
This is the most common finish produced and called for on sheet material. It is brighter than 2D and is semi-reflective. It is commonly used for most deep drawing operations, and is more easily polished to the final finished required than is a 2D finish.
No 2 BA Finish
This is more commonly referred to as a BRIGHT ANNEALED (BA) FINISH. Material with a No. 1 finish is Cold Rolled using highly polished rolls in contact with the steel surface. This smooths and brightens the surface.
The smoothness and reflectiveness of the surface improves as the material is rolled to thinner and thinner sizes. Any annealing which needs to be done in order to effect the required reduction in gauge, and the final anneal, is effected in a very closely controlled inert atmosphere. No oxidation or scaling of the surface therefore occurs and there is no need for additional pickling and passivating.
The final surface developed can have "MIRROR" type finish similar in appearance to the highly polished No. 7 and No. 8 Finishes.
Note
Much of the 2B Finish sheet imported is not a true 2B Finish. Mills which operate bright annealing facilities will often carry out all the annealing operations of Cold Rolled material in such facilities. This leads to a superior "2B" finish as no oxidation or scaling takes place during the annealing operation, even though the actual rolling may be effected on polished rolls as for normal 2B Finish, but not highly polished as would be needed to produce a BA finish.
The following finishes are all mechanically produced polished finishes. As well as being standard mill finishes, they are also applied to stainless steel articles and components to meet the required aesthetic criteria. It should be appreciated that factors such as hand polishing vs. mechanical polishing; polishing a flat product as against a component of complex shape; thickness and composition of material can affect the visual appearance of the final surface.
No. 3 Finish
This is a ground unidirectional uniform finish obtained with 80 - 100 grit abrasive.
It is a good intermediate or starting surface finish for use in such instances where the surface will require further polishing operations to a finer finish after subsequent fabrication or forming.
No. 4 Finish
This is a ground unidirectional finish obtained with 150 grit abrasive. It is not highly reflective, but is a good general purpose finish on components which will suffer from fairly rough handling in service (eg restaurant equipment).
No. 6 Finish
These finishes are produced using rotating cloth mops (Tampico fibre, muslin or linen) which are loaded with abrasive paste.
The finish depends on how fine and abrasive is used, the uniformity and finish of the original surface.
The finish has a non-directional texture of varying reflectiveness. "Satin Blend" is an example of such a finish.
No. 7 Finish
This is a buffed finish having a high degree of reflectiveness.
It is produced by progressively using finer and finer abrasives and finishing with Buffing compounds. Some fine scratches (grit lines) may remain from the original starting surface.
No. 8 Finish
This is produced in an equivalent manner to a No. 7 Finish, the final operations being done with extremely fine buffing compounds.
The final surface is blemish free with a high degree of image clarity, and is the true mirror finish.
Note
The finer polished finishes (No. 4, No. 6, No. 7 and No. 8) are generally only produced one side of the sheet, the reverse side being either a 2B or No. 3 Finish.

Stainless steel is a versatile material comprised of a steel alloy and a small percentage of chromium—the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing. Based on the end use of the pipe, stainless steel piping is broken down into several categories.
Pipes and tubes are sometimes difficult to classify, and tend to be distinguished based on function. In addition to these classifcations, stainless steel is also distinguished by type and grade. For tubing and piping applications, type 304 stainless steel is a common selection because it is highly chemical- and corrosion-resistant. However, type 304 stainless steel is not compatible with applications where temperatures fall between 800 and 1640 degrees Fahrenheit (F) because it is prone to carbide precipitation, a result of the material’s .08 percent carbon content limit. Stainless steel type 304L circumvents this problem because it has a lower carbon content limit, and therefore can be subjected to welding and higher temperature applications. Other types of stainless steel often possess additives (such as nickel or molybdenum) which strengthen traits that are desirable in particular applications.
This general category of steel is appropriate for applications that require corrosion resistance above other traits. Ferritic or martensitic types of steel (those made with the most chromium) are manufactured to be either heat-treated or annealed. Austenitic Stainless steels (those with high chromium and nickel contents) offer even more resistance, and can be used under the same general conditions as ferritic and martensitic types.
This type of stainless steel pipe is made from either solid chromium or a chromium and nickel combination. Types of stainless steel pressure pipe include seamless and welded pipe, electric fusion welded pipe for high-pressure applications, large diameter welded pipe for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel pipe.
For applications where stainless steel tubing or piping must come into contact with food and other sensitive products, sanitation is a high priority. Stainless steel sanitary tubing is used in such applications because it has high corrosion-resistance, doesn’t tarnish, and is easy to keep clean. For specific applications, different tolerances can be achieved. The grade typically used for these applications is ASTM A270.
In applications such as cylinders, bearings, and other hollow formed parts, stainless steel mechanical tubing is typically used. Tubing can manipulated to have a variety of cross-sectional shapes, such as square and rectangular, in addition to the more traditional, round tubing cross-section. Typically, ASTMA 511 and A554 grades are employed for mechanical tubing applications.
In highly-specific aircraft applications, chromium and nickel type stainless steel is used because of their heat and corrosion-resistance. Found in applications that require high-strength, stainless steel aircraft tubing can be work-hardened or welded, although work-hardened pieces shouldn’t be used with some kinds of corrosive substances. Low-carbon types of stainless steel are a common choice for welded parts.
For applications that require seamless and welded tubing in larger sizes (1.6 to 125 mm in outside diameter), aircraft structural tubing is used—this type of stainless steel is manufactured according to Aerospace Material Specifications (AMS) or Military Specifications (MIL Specs).
Aircraft Hydraulic-Line Tubing, another type of aircraft tubing, is used in aerospace applications as fuel-injection lines and hydraulic systems, and tends to be small. It is often manufactured from types 304 or 304 L stainless steel because of the steel’s high-strength, corrosion-resistance, and ductility.

As you can see, Stainless steel pipe applications are huge and have became a natural option for heat and corrosion resistance metal.
ERW Welded SS tubes and pipes are ideally suitable for applications withing Oil & Gas, petrochemicals, chemical, pulp and paper, breweries etc.
Where low maintenance and corrosion resistance is required, stainless steel pipes are a natural choice and are used in a diverse range of applications and equipment (as mentioned above).
With so many different products like seamless pipes, welded pipes and flanges it might be overwhelming trying to pick which Stainless steel pipe to use for your business applications, or even what they can be used for in the first place. There are many different properties of each pipe that give it a unique use in its respective industries, and if you’re going to master the different types of piping materials and what they’re used for, it’s important that you learn the different types, what they can be used for and how they can be applied to various industries.
To give you a hand, we’ve put together a simple article that details most of the regular uses for Stainless steel pipe, why it’s used and how it could be applied to a generic industrial company.
First, let’s dive into the many different types of stainless steel pipe so that we can judge which types to use for each different scenario.
A seamless pipe is a pipe that does not contain any seams or weld joints. It’s capable of standing up to intense levels of pressure and also temperatures thanks to the metal itself. It’s used in a wide variety of different oil and gas applications, but they are also used in mechanical and engineering industries too. This makes seamless pipes rather versatile and they are always inspected with high levels of precision to ensure the quality of the material.
Welded pipes can be used in virtually every industry thanks to its flexibility. However, they fare better in corrosion resistance as opposed to withstanding pressure. Because of the materials used and the lightweight nature of welded pipes, they’re far more cost-effective than most other piping methods and offer the best value for your money.
Pipe flanges are another important part of your overall piping setup. These come in many forms such as slip-ons, blinds, lap joints, threaded and semis. These are made from durable and sturdy materials to ensure their reliability and high-quality products are always used when creating pipe flanges.
For permanent or long-term solutions that allow for isolation of piping sections, spectacle blinds, spades and spacers are used for convenience. If a piece of machinery or piping section needs to be inspected, then spectacle blinds are used so that you can isolate a certain part of the piping in order to maintain a larger system. Since this is an incredibly important role that is crucial to your safety, it’s recommended to rigorously test the reliability of your spectacle blinds if you want to remain safe. Given that each use case is different, it’s recommended that you speak with a professional first before investing a lot of money into spectacle blinds.
Now we’ve taken a look at the different types of steel pipe on offer, let’s look at the industries they are used in.
Technology plays a massively important role in the oil and gas industries. The need for corrosion-resistant piping has increased over the past couple of years as the depths we explore for oil deepens and more pressure is being placed on the duplex and super duplex stainless steel pipes we use. These harsh environments can be incredibly corrosive and if the damage is left unchecked, the pipes would easily burst and become unusable for deeper depths. This is why it’s important to have sturdy pipes in the oil and gas industry and how it plays such a huge role in the success of this industry.
Obtaining usable energy from atomic nuclei is no easy task. All of the nuclear reactors we use today heat water to produce steam which is then used to spin turbines that provide us with energy and most of them are placed near the coast due to the cooling requirements. As such, much of the water being pumped in to cool down these reactors is from the sea, and it needs to be resistant to the corrosive nature of seawater. Stainless steel pipe is more than qualified to defend against corrosion from seawater, hence its importance in thenuclear power industry.
LNG (liquefied natural gas) is gas that has been temporarily converted into a liquid form for the sake of transportation. Its volume is greatly reduced to make it easier and cheaper to transport. In some cases, transporting natural gas via pipelines isn’t possible or cheap enough to be worth the cost, which is why it’s instead transported via a liquid form in cryogenic sea vessels and road tankers. As such, it’s important to have the right piping that provides safe and economical LNG transport to deliver natural gas to parts of the country or world that are difficult to reach.
Desalination is the removal of salt and other minerals from a source of water. This is done to convert water into fresh water that is fit for humans to use or possibly irrigation. In most cases, salt is created as a by-product and desalination are used on many submarines and ships. Today, desalination is typically spoken about when attempting to bring fresh potable water to regions of the world where it is difficult. Saltwater and metals generally don’t mix very well, hence the importance of getting piping in the desalination industry that is able to withstand the natural corrosive properties of salt water.
Mining is the process of extracting materials from the earth. The materials covered are usually in the form of metals both common and precious and it’s something that has been done for thousands of years to acquire beneficial resources. The mining industry is one where stainless steel has made it easier and more profitable to take on larger operations. Whether it’s used in the actual mines itself where workers and machines dig at the earth, or in the bunk beds and mess halls where staff sleep, it’s used in a variety of different applications to provide safety and reliability.
