UNS NO6002 Wrought nickel-base superalloy

UNS NO6002 is a kind nickel base super alloy with Cr and Mo solid solution having a high iron content, strengthening, has good anti raising and corrosion resistance, moderate endurance and creep strength at 900 degree, cold, hot workability and good welding performance. The combustion chamber components used in the manufacture of aircraft engines and other high temperature components, long-term use under 900 degree, short-time working temperature can reach 1080 degree. The main varieties of supply of sheet, strip, pipe, bars, forgings, rings and precision casting.
