GH3128 is a nickel-based alloy solid solution 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. The alloy has a single-phase austenite structure in the solid solution state and contains a small amount of fine and evenly distributed TiN and M6C.

GH3128 alloy plateis suitable for manufacturing combustion chamber flame tubes of aeroengines that operate at 950°C for a long time, structural parts of gas turbine combustion chambers, turbine engine combustion chamber parts, afterburner casings, regulator plates, and other high-temperature parts.
The main products ofGH3128 alloyare cold-rolled sheets, but it can also supply hot-rolled plates, bars, forgings, wires, and pipes. The solid solution temperature in the delivery state is 1140~1180℃, air cooling. High-temperature performance is tested after supplementary solution treatment at 1200℃. Cold rolled sheet 0.8~4.0mm, hot rolled plate 4~14mm, cold drawn welding wire Φ0.3~10mm. Cold-rolled plates and hot-rolled plates are in solid solution and pickling; welding wire is in cold-drawn, semi-hard, or solid solution and pickling states.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
