To Be your reliable alloy solution supplier
GH4037
GH4037 (GH37) alloy is a nickel-base alloy with austenitic aging strengthening, and is formed by adding about 4% aluminum and titanium γ The phase is aging strengthened, and more tungsten and molybdenum are added for solid solution strengthening, and a small amount of boron is added to strengthen the grain boundary. The alloy is used below 850 ℃ and has high thermal strength, good comprehensive performance and structural stability. It is widely used in manufacturing aero-engine turbine blades and is used for a long time below 800-850 ℃. Application field: due to its moderate thermal strength and good thermal fatigue performance below 850 ℃, it can be widely used in aero-engine, combustion chamber, afterburner parts, acid environment, turbine working blades;
