Ore processing in metallurgy involves mineral extraction, a method wherein the ore has been separated from its valuable mineral. During the ore extraction process, chemically aggressive solids and fluids are used.

Which is why it is important that an appropriate material such as the    Hastelloy c276 bolts is used to build the equipment. Selecting a corrosion resistant material is like making a huge investment for ore processing equipment. What better than choosing nickel based Hastelloy c276 stud bolts! Whether resistance to pitting or to localized corrosion, the Hastelloy c276 nuts proves to be a well favoured choice across many ore processing plants.

Typically during the processing of various mineral ores, there is always a presence of thiosulfates, which in turn leads to small holes or deformities in conventionally used alloys. This is a major concern with ore processing. The ability of Hastelloy c276 forged rings to withstand harsh chemical environments is what makes this alloy an ideal material for ore processing equipment. A technique of extracting ores is Leaching, where the ore is treated with chemicals in order to convert the valuable metals into soluble salts while impurity remains insoluble. ASTM B574 UNS N10276 stud bolt used in this equipment is used to being a part of an oxidative leaching process.

In fact, these Hastelloy c276 fasteners can be used in oxidizing atmospheres up to a temperature of 1900°F. Moreover, the performance of Hastelloy c276 hex bolt tends to be excellent in high pressured environments. For instance, in the acid leaching process, the ASTM B574 bolts perform well at a pressure of about 5400 kPa. However, in environments that are strongly oxidising, the DIN 2.4819 bolt is susceptible to being attacked.

 

Check with your supplier

Hastelloy C276 Hex bolt comes in sizes from ‎M3 – M56. Bur always remember to ask from your supplier that your Alloy c276 fasteners are according to ASTM F467 / ASME SF467 and also check external threads spec should be ASME B1.1 2A/3A – 2B/3B Inch & B1.13M 6h-6G Metric with certificate NACE MR0103/MR0175/ISO 15156

Hastelloy C276 hex bolts vs 316 hex head bolt

The bolts and nuts are made in different material grades. The most common is the 304 grade and the second mostly used is the 316 grade. The c276 grade bolts are rare. The c276 hex bolts are used in high temperature applications with high corrosion prone operations. The 316 hex head bolts are used against general corrosion and chloride iron corrosion. The application of 316 hex head bolts can be seen in food grade applications, marine and sea water applications, water lines and in other general corrosive applications. These are cheaper compared to c276 alloy hex bolts. The c276 hex bolts are used in chemical processing applications mostly. They do not corrode easily under severe conditions such as concentrated acids, alkalis and in heat exchangers at very high temperatures as well.
