High Temperature Alloy
High Temperature Alloy
◆GH2132 (incoloyA-286/S66286) has good overall performance and high yield limit. It is used for turbine discs, ring bodies, bracket weldments and compensation parts materials below 700 °C.
◆GH3030 alloy has a stable structure, less aging, and good oxidation resistance. It is suitable for combustion chambers and afterburners below 800 °C.
◆GH3128 has good comprehensive performance, high durability, good oxidation resistance, good structural stability and good welding function, and is mainly used for the combustion chamber and afterburner parts of the turbine engine with an operating temperature of 950°C
◆GH4145 (inconelx-750/N07750) has sufficient strength, corrosion resistance and oxidation resistance below 980°C. It is the preferred material for high-strength springs and is suitable for making elastic diaphragms and elastic sealing sheets.
◆GH4169 (N07718/inconel718) has an austenite structure, and the "Y" phase formed after precipitation hardening makes it have excellent mechanical properties. It is widely used in various places with high temperature resistance requirements.
◆GH4080A (N07080/Nimonic80A)Z has sufficient high temperature at 700-750°C and good oxygen resistance below 900°C. This special alloy is suitable for fields requiring high strength and corrosion resistance.
◆GH3044 Main combustion chamber and afterburner components, heat shields, guide vanes, etc.
◆GH4080A has good creep resistance and oxidation resistance in the range of 650-850°C.
◆GH2136 has good overall performance, stable structure after long-term use, good oxidation resistance, small linear expansion coefficient, and easy welding and forming.
◆GH2036 Turbine discs, heat shields, retaining rings, bearing rings, fasteners, etc. that work below 650 °C.
◆GH4738 is suitable for making turbine discs, working blades, high-temperature fasteners, flame tubes, shafts and turbines, etc.
