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