What is Hastelloy alloy B-2?

Hastelloy B-2 alloy is a Ni-Mo alloy with extremely low carbon and silicon content.

Hastelloy B-2 alloy, also known as Hastelloy B-2 alloy, is a nickel-molybdenum alloy with excellent corrosion resistance. Its characteristics include extremely low carbon and silicon content. This chemical composition design helps to reduce the precipitation of carbides and other phases in the weld and heat-affected zone during the welding process, thereby ensuring that even under welding conditions Can maintain good corrosion resistance.

In addition, Hastelloy B-2 alloy also has the following properties:

Control the content of iron and chromium at the lowest level to prevent the formation of β-phase Ni4Mo.
Excellent corrosion resistance to reducing environments.
Excellent resistance to corrosion by moderate concentrations of sulfuric acid and many non-oxidizing acids.
Very good resistance to chloride ion reduction stress corrosion cracking (SCC).
Excellent resistance to corrosion by various organic acids.
