Hastelloy® B Foil

Hastelloy® B Foil is a thin, high-performance nickel-molybdenum alloy foil prized for its excellent resistance to strong reducing environments, particularly hydrochloric acid and other aggressive chemicals. Its combination of low carbon content and high molybdenum ensures strong resistance to localized corrosion, such as pitting and stress corrosion cracking. Industries such as chemical processing, energy, and advanced manufacturing rely on Hastelloy® B foils for their ability to act as corrosion-resistant barriers and precision-engineered layers in composite systems. Specific technologies benefiting from Hastelloy® B foil include explosive welding with steel to create durable Hastelloy-steel layered composites for demanding environments, radiation shielding applications where Hastelloy B demonstrates superior attenuation properties compared to conventional materials, and electrode substrates or claddings for harsh chemical processing systems. In research and innovation, Hastelloy® B foil enables studies on joining techniques, corrosion behavior, and alloy performance under extreme conditions, making it indispensable for both industrial applications and scientific advancements in advanced alloy technology.
