Hastelloy

Nickel-molybdenum-chromium superalloys offering exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive chemical environments.

Supplied solution annealed. bright / cold drawn surface finish; near-nickel matrix offering outstanding performance in non-oxidizing acids, acetic and phosphoric service. Ideal for shafts, fasteners & precision machined parts.
Supplied solution annealed. mill / polished surface finish; improved thermal stability over earlier B-2 grades, resisting knife-line and heat-affected-zone attack. Ideal for pressure vessels & chemical processing equipment.
Supplied solution annealed. as forged / machined surface finish; outstanding resistance to reducing acids such as hydrochloric and sulfuric, with low carbon to prevent weld decay. Ideal for forged components, flanges & rings.
Supplied solution annealed. bright / soft surface finish; good resistance to wet chlorine gas, hypochlorite and chlorine dioxide, making it a preferred scrubber alloy. Ideal for screening, welding & fasteners.
Supplied solution annealed. bright / rolled surface finish; virtually immune to chloride-induced pitting and crevice corrosion, with 869 g/cm3 density.
Supplied solution annealed. mill / bright annealed surface finish; versatile nickel-chromium-molybdenum resistance to both oxidizing and reducing media, outperforming C276 in mixed-acid service. Ideal for heat exchangers & process piping.
