Hastelloy fasteners are composed of nickel-chromium-molybdenum alloys, featuring well-known grades such as C-22 and C-276. These alloys offer remarkable resistance to corrosive substances like acids, oxidizers, and chlorides. Typically, the fasteners boast tensile strengths between 690 and 760 MPa and yield strengths ranging from 280 to 355 MPa. Their outstanding thermal stability and toughness enable them to maintain their integrity even under high temperatures and pressures. Plus, the low carbon content helps reduce the risk of sensitization and intergranular corrosion, ensuring dependable performance in harsh chemical and marine settings.
