The fasteners also have great localized corrosion attack resistance. Heat treatment after welding is not necessary for these fasteners if welded. The tensile strength of the Hastelloy C276 Hex Nuts is 758MPa and the minimum yield strength is 379MPa. The specification for this alloy is ASTM B574.
The material contains nickel – cobalt base, chromium 16%, molybdenum 16%, tungsten, iron, silicon, manganese, carbon and other metals. Because of its composition, the ASTM B574 Uns N10276 Nut Bolts are also and cost higher than the other stainless steel and alloy steel material made fasteners. Due to the high resistance of the material, these fasteners are used in chemical processing, acid processing, food processing and in other high corrosive or high sensitive applications.
