Shandong PipeNil Metal Products Co., Ltd

Hastelloy B-3 has excellent corrosion resistance to hydrochloric acid of all concentrations and temperatures, and also has effective resistance to reducing environments such as sulfuric acid, phosphoric acid, formic acid, acetic acid and other non-oxidizing media. It also resists pitting corrosion, stress corrosion cracking, edge and weld heat affected zone corrosion. Hastelloy B-3 has better thermal stability than B-2

Physical properties

Density: 9.22 g/cm3

Melting point: 1370-1418℃

characteristic:

Hastelloy B-3 has excellent corrosion resistance to hydrochloric acid of all concentrations and temperatures, and also has effective resistance to reducing environments such as sulfuric acid, phosphoric acid, formic acid, acetic acid and other non-oxidizing media. It also resists pitting corrosion, stress corrosion cracking, edge and weld heat affected zone corrosion. Hastelloy B-3 has better thermal stability than B-2.

application:

Hastelloy B-3 has the same application fields as B-2, but like B and B-2, Hastelloy B-3 is extremely susceptible to corrosion in oxidizing environments and therefore cannot be used in environments containing iron salts or copper salts because these Substances can quickly cause corrosion.
