inconel 713c k418, k18, w.nr. 2.4670 is'Phase precipitation strengthened nickel-based cast superalloy. It has good creep strength, thermal fatigue properties and oxidation resistance below 900°C. The alloy composition is simpler, does not contain cobalt, has a lower density, and is usually used in the as-cast state. 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 with degraded and reduced properties after long-term use. Long-term aging at 800°C will precipitate a small number of phases, but there is no significant effect on performance. This alloy is suitable for making turbine rotor blades, guide vanes and cast turbines and other high-temperature parts of gas turbines operating below 900.
Fields of application. The alloy has been widely used in aviation, ground and offshore gas turbine turbine working blades, guide vanes and cast turbines working below 900°C, and is also widely used in diesel and gasoline engine supercharged turbines and hot extrusion dies. The alloy has been proved by the long-term production and use practice of more than 1,000 tons of more than 1000 manufacturers with stable metallurgical quality and reliable performance, and is widely used as turbine working blades and guide vanes of various aero engines. When used for a long time under hot corrosive conditions, the metal must have a protective coating.
