Hastelloy B2 Alloy is designed to be used in extreme reducing conditions.

Hastelloy B2 is high nickel-molybdenum-chromium alloy providing excellent resistance to corrosion against all acidic environments such as hydrochloric acid with all temperatures.Its chemical composition provides strength against all acids such as hydrogen chloride, sulfuric, acetic and phosphoric acids. Hastelloy B2 gives resistance to pitting, to stress corrosion cracking and to all organic and non-organic acidic environment. Alloy B2 resists the formation of grain boundary carbide which precipitates in the welding area of the metal so is used against the chemical process application in the welded condition.
