SJNQ-63002（code）K418/IN713C
K418 is a nickel-based precipitation-hardened high-temperature alloy, with a working temperature of up to 900°C. The alloy exhibits high creep strength, excellent thermal fatigue resistance, and oxidation resistance. It is typically used in the as-cast condition. This alloy is applied in the hot-end rotating and stationary precision castings of gas turbines, such as rotor blades, guide vanes, diffusers, and integral cast turbines. The K418 alloy produced by our company can meet customer requirements for mechanical properties, as well as specific oxygen and nitrogen content.
