Hastelloy B-2
Description: Hastelloy B-2 / N10665 / NS322 / 2.4617
Features: Hastelloy B-2 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also has significant resistance to reducing environments like sulfuric, phosphoric, acetic acids and other nonoxidizing media. Hastelloy B-2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Hastelloy B-2 has poor resistance to oxidizing environments, therefore, it should not be used where ferric or cupric salts are present as these salts may cause rapid corrosion failure.
Applications: Equipment handling reducing chemical environments; and chemical process industry involving hydrochloric, sulfuric, phosphoric and acetic acids.
