Haynes International, a specialist in high-performance alloys, announced that it has developed a new alloy, HAYNES 244. The alloy possesses excellent resistance to oxidation at temperatures ranging up to 760°C.
In addition, HAYNES 244 has exceptional thermal stability, low thermal expansion behavior and high temperature strength. The alloy is formulated using nickel (Ni), cobalt (Co), molybdenum (Mo) and tungsten (W). The Ni–Mo-Cr-W alloy also provides outstanding forging and ductility features. HAYNES 244 gains superior strength via an aging heat treatment process and the thermal expansion property of the alloy is lower than 242 alloy and other low expansion commercial superalloys. Also, tensile and creep characteristics of the new alloy surpasses the HAYNES 242 alloy.
HAYNES 244 alloy is produced in various product forms such as plate, bar and billet. It has wide range of applications, including land-based gas turbines and aircraft such as seamless forged cases and rings. Once additional product developments are completed, this high strength material from Haynes International will be available commercially. The trial will be carried out on the alloy as the manufacturing continues.
Haynes International develops, manufactures and markets advanced cobalt and nickel-based high-performance alloys that are used mainly in the land-based gas turbine, chemical processing and aerospace industries.
