Haynes 25
Description:
Haynes 25 (UNS R30605 / W.Nr 2.4964) is a cobalt-nickel- chromium-tungsten alloy that combines excellent high-temperature strength with good resistance to oxidizing environments up to 980¡æ 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.
Features:
Outstanding high temperature strength
Oxidation resistant to 1800¡ã F
Galling resistant
Resistant to marine environments, acids and body fluids
Haynes 25 Applications:
Gas turbine engine combustion chambers and afterburners
High temperature ball bearings and bearing races
Springs
Heart valves
