GH3128 (GH128) is a nickel-based alloy with tungsten and molybdenum solid solution strengthening and grain boundary strengthening with boron, cerium and zirconium.
It has high plasticity, high lasting creep strength, good oxidation resistance, stamping, welding and other properties. .
Its comprehensive performance is superior to similar nickel-based solid solution alloys such as GH3044 and GH3536.
It is suitable for manufacturing the combustion chamber flame tube, afterburner casing, regulating plate and other high-temperature parts of aero-engines that work for a long time at 950 °C.
The main products are cold-rolled sheets, and hot-rolled sheets, bars, Forgings, wire and tubing. The solution temperature in the delivery state is 1140-1180ºC, and it is air-cooled.
The high temperature performance is tested after supplemental solution treatment at 1200ºC.
Cold rolled sheet 0.8~4.0mm, hot rolled sheet 4~14mm, cold drawn wire Φ0.3~10mm.
Cold-rolled sheet and hot-rolled sheet are in solution and pickling; welding wire is in cold drawn, semi-hard or solid solution and pickling state.
Non-vacuum or vacuum induction furnace plus electroslag remelting.
The alloy is suitable for the manufacture of aero-engine combustion chamber and afterburner parts that work below 950 °C, and the use effect is good.
