1.\u00a0<\/span><\/strong>Introduction to GH3128 Materials<\/span><\/strong>\u00a0<\/strong><\/p>\n

\u00a0 \u00a0 \u00a0 GH3128 (GH128) is a nickel-based alloy that uses tungsten and molybdenum solid solution strengthening and strengthens grain boundaries with boron, cerium and zirconium. It has high plasticity, high long-lasting creep strength, good oxidation resistance and 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 the combustion chamber flame cylinder, afterburner combustion chamber shell, adjustment sheet and other high-temperature parts of aircraft engines that work at 950\u00b0C for a long time. The main products are cold-rolled thin plates, and hot-rolled plates, bars, forgings, wires and pipes can also be supplied.<\/span><\/p>\n
