Hastelloy B-2


UNS Number N010665

Hastelloy B-2 has the features of hydrochloric acid resistance at any concentrations & temperatures and reducing environments. What’s more, Hastelloy B2 is also resisted to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Since the poor resistance to oxidizing environments, Hastelloy B2 should not be used in ferric or cupric salts environment in case of rapid corrosion failure. 

Hastelloy B2 is applied in these area, like Equipment handling reducing chemical environments; and chemical process industry involving hydrochloric, sulfuric, phosphoric and acetic acids.
