Hastelloy B-3 is a nickel-molybdenum alloy that has excellent resistance to pitting, corrosion and stress corrosion cracking, and better thermal stability than the B-2 alloy. In addition, this nickel steel alloy has strong resistance to knife line and heat affected zone attack. Alloy B-3 can also withstand sulfuric, acetic, formic and phosphoric acids and other non-oxidizing media. In addition, this nickel alloy has excellent resistance to hydrochloric acid at all focuses and temperatures.
