GH3128 Alloy

GH3128 (GH128) is a nickel-based alloy strengthened by solid solution of tungsten and molybdenum and strengthened by grain boundaries of boron, cerium and zirconium. It has high plasticity, high creep strength, good oxidation resistance, stamping and welding 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 housings, regulating plates and other high-temperature parts of aircraft engines that work for a long time at 950℃. The main products are cold-rolled thin plates, and hot-rolled plates, bars, forgings, wires and pipes can also be supplied.
