HAYNES 25
HAYNES 25 alloy (UNS R30605) is a cobalt-nickel-chromium-tungsten alloy that combines
excellent high-temperature strength with good resistance to oxidizing environments up to 980°C for prolonged exposures, and excellent resistance to sulfidation. It can be fabricated and formed by conventional techniques, and has been used for cast components. Other attractive features include excellent resistance to metal galling.
