Description
Hastelloy B3
HASTELLOY® B-3® alloy (UNS N10675) exhibits extremely high resistance to pure hydro-chloric, hydrobromic, and sulfuric acids. Furthermore, it has greatly improved structural stability compared with previous B-type alloys, leading to fewer concerns during welding, fabrication, and service.
