GH3030 is an early developed 80ni-20cr solid solution strengthened high-temperature alloy with simple chemical composition, good hot strength and high plasticity below 800 ℃, good oxidation resistance, thermal fatigue resistance, cold stamping and welding process performance. The alloy after solution treatment is single-phase austenite, and the structure is stable during use. The main products are cold-rolled plates, and can also supply bars, rings, wires, pipes and other profiles. Mainly used for turbine engine combustion chamber parts working below 800 ℃ and other high temperature parts requiring oxidation resistance below 1100 ℃ but with small load.
Gh3039 is a single phase austenite solid solution strengthened alloy. It has moderate thermal strength and good thermal fatigue performance below 800 ℃, and good oxidation resistance below 1000 ℃. The structure is stable, the cold formability is good, and the weldability is good. It is suitable for long-term use of aero engine combustion chamber and afterburner parts below 850 ℃. The alloy can be used for plates, bars, wires, tubes and forgings.
GH3044 is a solid solution strengthened nickel base oxidation resistant alloy. High plasticity, moderate thermal strength below 900 ℃, excellent oxidation resistance and good stamping and welding process performance. It is suitable for manufacturing the main combustion chamber, afterburner components, heat shield, guide vane, etc. under 900 ℃ for long-term operation.
Gh3128 is a nickel-based alloy, tungsten, molybdenum solid solution strengthening, boron, cerium, zirconium grain boundary strengthening. It has high plasticity, high creep rupture strength, good oxidation resistance, stamping and welding performance. Its comprehensive performance is better than GH3044 and GH3536. It is suitable for the manufacture of high temperature parts such as flame tube, afterburner shell and regulating plate of aeroengine combustion chamber working at 950 ℃ for a long time. The main products are cold-rolled plates, and hot-rolled plates, bars, forgings, wires and pipes can also be supplied.
Gh4080a is a nickel-based high-temperature alloy composed of nickel-chromium alloy, which has good strength, excellent high-temperature corrosion resistance and oxidation resistance. These advantages make 4080a widely used in aviation, aerospace, power station, transportation and other high temperature hot forging parts.
The disc spring is a conical disc and can be used alone or in series or parallel. Undertake dynamic load along the upper or lower edge. When compressed, it deforms until it flattens. It can be used as a live load in the form of stored energy, automatically converted to the additional compression load required for sealing when necessary, supplementing the continuous requirements of gaskets and packing, maintaining the rated load, and reducing unnecessary downtime and leakage losses.
