Product Overview
Inconel 713C (K418) is a mature, cobalt-free nickel-based γ' phase precipitation-hardening high-temperature alloy produced by Qinchuan New Materials (Zhengzhou) Co., Ltd. The alloy, with its γ' phase strengthening mechanism, boasts excellent high-temperature mechanical properties, high cost-performance ratio, and excellent casting properties. The Inconel 713C alloy maintains stable performance at long-term service temperatures of ≤900°C and can withstand peak temperatures up to 950°C for short periods. It is widely used in high-temperature hot-end components of the aerospace, gas turbine, power machinery, petrochemical metallurgy, and other fields.
Main Product Features
- Excellent high-temperature comprehensive performance: high temperature resistance, creep resistance, thermal fatigue resistance, strong oxidation resistance, stable structure and high strength retention below 900°C.
- Excellent precision casting performance: strong casting fluidity and filling capability, suitable for vacuum investment casting, and ideal for shaping various complex precision hot-end parts.
- Flexible and high stability: Cast state can be used directly without complex pre-treatment; further improvement in plasticity and fatigue resistance can be achieved through solution heat treatment + aging heat treatment.
- High cost-performance and wide compatibility: Cobalt-free formula reduces costs while maintaining performance comparable to high-end cobalt-containing high-temperature alloys; paired with protective coatings to enhance corrosion resistance for harsh thermal and sulfuric conditions.
