Nickel Alloy B Features:

Alloy B has excellent resistance to reducing environments like sulfuric acid at moderate concentrations and other nonoxidizing acids. It also resists stress corrosion cracking induced by chlorides. Hastelloy B 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.

 

Alloy 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. Alloy B-2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Alloy 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.

 

Nickel Alloy 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. Alloy B-3 has greater thermal stability than Alloy B-2.
