Hastelloy B2 Fasteners

AISI 4130 Bolts

Hastelloy B2 Fasteners are excellent choice in applications involving hydrogen chloride gas, sulfuric, acetic and phosphoric acids as the alloy exhibit excellant resistance to reducing agents. Boltport Fasteners offers wide range of fasteners in Hastelloy B2 including bolts, screws, stud bolts, threaded rods, nuts, washers and custom bolting parts in metric and imperial sizes.

Hastelloy® B2

Hastelloy B2 is a solid solution strengthened, nickel-molybdenum alloy, with significant resistance to reducing environments like hydrogen chloride gas, and sulfuric, acetic and phosphoric acids. This Nickel Alloy B2 provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack. Alloy B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids.
