ASTM B619 / B626 Alloy B-3 / UNS N10675 Nickel Alloy Welded tube/pipe

ASTM B619 / B626 Alloy B-3 / UNS N10675 Nickel Alloy Welded tube/pipe   

Alloy B-3 alloy is an additional member of the nickel-molybdenum family of alloys with excellent resistance to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B-3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. Alloy B-2 alloy. B-3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.

 Characters:

1. Maintains excellent ductility during transient exposures to intermediate temperatures；
2. Excellent resistance to pitting and stress-corrosion cracking
3. Excellent resistance to knife-line and heat-affected zone attack；
4. Excellent resistance to acetic, formic and phosphoric acids and other non-oxidizing media
5. Resistance to hydrochloric acid at all concentrations and temperatures；
6. Thermal stability superior to alloy B-2.
