Hastelloy C-276 (UNS N10276, 2.4819) is a nickel-molybdenum-chromium bolting grade with a 425°C service limit, supplied to ASTM B574 and B575 at 790 MPa tensile and 355 MPa yield in the solution-treated condition. The 15-17% molybdenum and 3-4.5% tungsten let hastelloy c276 bolts and hastelloy c276 fasteners resist both oxidising and reducing media: wet chlorine, hypochlorite, ferric and cupric chlorides, hot contaminated mineral acids and sour gas.
Specifications
Composition in wt% per ASTM B574. Balance and residuals verified by 100% PMI on every lot.
Hastelloy C-276 questions we get most
Wet chlorine, hypochlorite, chlorine dioxide, ferric and cupric chlorides, hot contaminated sulphuric and phosphoric acids, seawater and sour gas with H₂S. Hastelloy bolts resist both pitting and crevice attack and are effectively immune to chloride stress corrosion cracking.
