Description

Haynes® 25/L605 is a nonmagnetic, Cobalt-Nickel-Chromium-Tungsten alloy that combines excellent high temperature strength with good resistance to oxidization and carburization in environments up to 980°C (1795°F) for long exposures. It also has excellent resistance to sulphidation. Haynes® 25/L605 responds very well to cold working.
