Hastelloy B

Hastelloy B has a great ability of reducing environments, such as sulfuric acid at moderate concentrations and other nonoxidizing acids. Meanwhile, It also resists stress corrosion cracking induced chlorides. Since the poor resistance to oxidizing environments, Hastelloy B should not be used in ferric or cupric salts conditionss to avoid rapid corrosion failure. 

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