Hastelloy B- 3
Common Trade Names: Hastelloy B3; Alloy B3;
HASTELLOY B- 3 alloy (UNS N10675) is an excellent resistance alloy to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B- 3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, HASTELLOY B- 2 alloy. B- 3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.
