Product Description

Features:

UNS Number N010675

Hastelloy B-3 has a great hydrochloric acid resistance at any 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. Hastelloy B3 has greater thermal stability than Hastelloy B2.

Applications:
Hastelloy B3 is suit for the applications where Hastelloy B2 is required. Hastelloy B3 should not be used in the presence of ferric or cupric salts as these salts may cause rapid corrosion attack.
