Hastelloy Pipe Fittings, ASTM B366 UNS N10675 / Alloy B3 / DIN
2.4600 Stub End
Hastelloy B3 / UNS N10675 is Nickel-Molybdenum Alloy similar to Alloy B2 in terms of
Resistance to Non Oxidizing agents, resistance to stress corrosion
& pittings, non formationof grain boundry but was designed with
addition quality of Thermal stability which improves welding
preparations. It 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.
