Hastelloy B-3

Description: Hastelloy B-3 / N10675 / NS323 / 2.4600

features: Hastelloy B-3 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also resists sulfuric, phosphoric, formic, acetic acids and other nonoxidizing media. It has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Hastelloy B-3 has greater thermal stability than Hastelloy B-2.

Applications: Hastelloy B-3 is suitable for the applications where Hastelloy B-2 is required. Like Hastelloy B-2, Hastelloy B-3 should not be used in the presence of ferric or cupric salts as these salts may cause rapid corrosion attack.
