    STAINLESS STEEL

    A193 B6 – Heat treated 410 stainless (410HT)

    A193 B8 – Produced to grade AISI 304, carbide solution treated, standardly available in class 1

    A193 B8M – Produced to grade AISI 316, carbide solution treated, standardly available in class 1

    A193 B8C- Grade 347 stainless material

    A193 B8T – Grade 321 stainless material

    A320 B8 - Produced to grade AISI 304, carbide solution treated, standardly available in class 1

    A320 B8M - Produced to grade AISI 316, carbide solution treated, standardly available in class 1

    A193 VS A320

    A193 is the ASTM standard covering alloy and stainless steel bolting materials for high temperature or high-pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Material selection depends on design, service conditions, mechanical properties, and temperature characteristics. This material is often available in UNC thread pitches. If being used in traditional applications, threads are specified 8 threads per inch or 8UN for diameters above one inch.

    A320 is the ASTM specification covering alloy steel and stainless bolting materials used in low-temperature services. A320 covers rolled, forged, or strain hardened bars, bolts, and stud bolts used for pressure vessels, valves, flanges, and fittings. As in A193, UNC threads are available but 8UN is standard on fasteners larger than 1" in diameter.

    CLASS 1 VS CLASS 2 STUD BOLTS

    Class 1 stud bolts are made from solution-treated material. Class 2 stud bolts are made from solution-treated material that has been strain hardened. Austenitic steels in the strain hardened condition may not show uniform properties throughout the cross section, particularly in stud bolt sizes over 3/4" diameter.  For instance, A193 B8 and B8M stud bolts are standardly provided as class 1 but are also available in class 2.

    DUAL CERTIFIED STUD BOLTS

    Many stud bolts are provided as "dual certified," meaning they conform to multiple sets of ASTM standards. Example: A193 B7 stud bolts can meet the requirements of A320 L7; B8 and B8m stud bolts also typically conform to both A193 and A320.

    Stainless Steel Fasteners Faq

    Is a Grade 8 bolt stronger than stainless steel?
    It is a common misconception that stainless steel is stronger than regular steel. ... Therefore, when compared to regular steel, the stainless alloys used in bolts are slightly stronger than an un-hardened (grade 2) steel but significantly weaker than hardened steel fasteners.

    Can you use stainless steel screws in aluminum?
    Stainless steel fasteners in aluminium plates or sheets are normally considered safe, whereas aluminium rivets or bolts holding stainless steel parts together is an unwise combination, as there is a practical risk of corrosion. ... Even with no insulation between the metals, there should be little risk of corrosion.

    What grade is a2 70?
    A Bolt Marked A2-70 Is A 304 Stainless Steel Bolt With A 700 N/mm2 Tensile Strength (See Below Table). The -70 Representing The Tensile Strength Divided By 10. -50 & -80 Grades Are Also Available But Are Not All That Common.

    Is a2 stainless steel the same as 304?
    SAE 304 stainless steel also known as A2 stainless steel (not the same as A2 tool steel) or commercially as 18/10 or 18/8 stainless steel, European norm 1.4301, is the most common stainless steel. The steel contains both chromium (between 18-20%) and nickel (between 8-10.5%) metals as the main non-iron constituents.

    Is magnetic stainless steel a2?
    A basic stainless steel has a 'ferritic' structure and is magnetic, formed from the addition of chromium – it can be hardened through the addition of carbon, making it 'martensitic'. However, the most common stainless steels are 'austenitic' – these have a higher chromium content and nickel is also added.

    What is a Grade 8 bolt?
    A grade 8 bolt is stronger than the more commonly used grade 5. It is made of alloy steel and has six radial lines on the top of the bolt head. Grade 8 bolts have a tensile strength of 150,000 pounds per square inch.

    What does grade 5 bolt mean?
    Well, we'd like to explain the technical difference between a SAE Grade 8 (Grade 8) and a SAE Grade 5 (Grade 5) fastener. Most people think a bolt is a bolt is a bolt. They see it as a machined chunk of metal that holds or attaches things. Fasteners (aka bolts or screws) are complex mechanically-engineered hardware.

    What is the difference between a325 and Grade 8 bolts?
    A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325. An ASTM specification with similar strength properties to grade 8 is ASTM A490.

    What is a2 grade stainless steel?
    The two most commonly produced grades of stainless steel are 304 (known as 'A2') and 316 (known as A4). Both of these grades will offer excellent corrosion resistance, cleanability, and the ability to handle extremely low (cryogenic) and high temperatures.

    What is a4 80 stainless steel?
    The “80” denotes the minimum tensile strength to be met by the material (actually the bolt, screw or nut after manufacture). Therefore, A4-80 is an austenitic, acid proof stainless grade (usually 316 material - 316 or 316L) which has been cold worked to provide a minimum tensile strength of 800 N/mm2 (MPa).

    How strong is a 10.9 bolt?
    A tempered medium carbon steel. Class 10.9 is stronger than class 8.8, and is commonly found in high strength automotive applications. Class 10.9 is similar to grade 8. Zinc plated for moderate corrosion resistance.

    What is the difference between a325 and Grade 8 bolts?
    A325 bolts are typically manufactured from a medium carbon steel (although they can be made from an alloy) while SAE grade 8 bolts are made from a medium carbon alloy steel. Grade 8 bolts are significantly stronger than an A325. An ASTM specification with similar strength properties to grade 8 is ASTM A490.

    How strong is a 10.9 bolt?
    A tempered medium carbon steel. Class 10.9 is stronger than class 8.8, and is commonly found in high strength automotive applications. Class 10.9 is similar to grade 8. Zinc plated for moderate corrosion resistance.

    What does 8.8 mean on the head of a bolt?
    If you have ever looked a metric hex bolt you might notice the markings 8.8, 10.9 or 12.9 this does not mean grade 8,10 or 12. The grade 8.8 refers to the tensile strength which is generally 116,000 psi, grade 10.9 is generally 150,000 and grade 12.9 is generally 175,000 psi.

    What is 8.8 grade bolt?
    These are grade 4.6 and 8.8. The first digit relates to the ultimate strength of the material, whilst the second is the ratio of yield stress to ultimate strength. Thus grade 4.6 bolts have an ultimate material strength of 400N/mm2 and the uield (or proof) stress is 60% of the ultimate strength.
