inconel 713C is a γ' phase precipitation strengthened nickel-based casting superalloy. It has good creep strength, thermal fatigue performance and oxidation resistance below 900℃. The alloy composition is relatively simple, does not contain cobalt, has a low density, and is usually used in the cast state. The use of hot isostatic pressing (HIP) treatment and subsequent heat treatment can improve the plasticity and fatigue properties, and can also restore the structure and performance of parts that have undergone structural degradation and reduced performance after long-term use. A small amount of σ phase will precipitate during long-term aging at 800°C, but it will have no significant impact on performance. The alloy is suitable for making turbine rotor blades, guide vanes, monolithic turbines and other high-temperature parts of gas turbines operating below 900°C.
Application overview and special requirements? This alloy has been widely used as turbine blades, guide vanes and integral cast turbines for aviation, ground and offshore gas turbines operating below 900°C. It is also widely used in diesel and gasoline engine superchargers. Turbine and hot extrusion dies. The long-term production and use of more than 1,000 tons of this alloy by more than a dozen manufacturers has proven that it has stable metallurgical quality and reliable performance. INC0713C alloy, which is equivalent to this alloy, is widely used as various aero-engine turbine blades and guide blades abroad. This alloy must have a protective coating when used for long periods under hot corrosive conditions.
