Hastelloy B2 Foil is a nickel-molybdenum alloy resistant to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. It also offers good resistance to stress corrosion cracking in oxidizing and reducing environments. The composition of Hastelloy B2 Foil includes approximately 44% nickel, 19–22% chromium, 14–17% molybdenum, 1.5–3% tungsten, and small amounts of cobalt, manganese and iron.
Hastelloy B2 foil is an alloy of nickel, molybdenum, and chromium with excellent corrosion resistance to various corrosive media. It has good thermal stability and mechanical strength at high temperatures. This makes Hastelloy B2 foil particularly useful in chemical processing, pharmaceuticals, pollution control equipment, oil & gas production, power generation and aerospace. Its superior performance makes it ideal for applications requiring extended service life under severe operating conditions.
