This Nickel-Molybdenum alloy gives excellent resistance to hydrochloric acid at all concentrations and temperatures from ambient to high. It also withstands sulphuric, acetic, formic and phosphoric acids and other non-oxidizing media. B3 also has excellent resistance to pitting corrosion and to stress-corrosion cracking. Hastelloy B3 is not recommended in the presence of ferric or cupric salts. Like other nickel alloys, Hastelloy B3 is ductile and can be formed and welded. It resists stress corrosion cracking in chloride-bearing solutions, and is able to withstand fluoride-bearing media and concentrated sulfuric acid, both of which result in damage to zirconium alloys.
Diameter: 0.1 - 40mm
Shape: round, square, flat, special shaped
Hastelloy B3 offers the following key features:
