Introduction
GH3128(GH128) is a nickel-based solid solution alloy reinforced with tungsten and molybdenum and grain boundaries reinforced with boron, cerium and zirconium. It has high plasticity, high lasting creep strength, good oxidation resistance and stamping, welding and other properties. . Its comprehensive performance is better than similar nickel-based solid solution alloys such as GH3044 and GH3536. It is suitable for manufacturing combustion chamber flame tubes, afterburner casings, regulator plates and other high-temperature parts of aeroengines that operate at 950°C for a long time.
