Alloy B Pipe/Tube, Flanges, Fittings

Chemical composition










Physical properties

Density9.24 g/cm3
Melting range1330-1380℃

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.

Applications: Equipment handling reducing chemical environments; and chemical process industry involving hydrochloric, sulfuric, phosphoric and acetic acids.

Note: Hastelloy is a registered trademark of Haynes International, Inc.
