Inconel is a family of nickel-based superalloys, primarily alloyed with chromium, iron, molybdenum, and niobium. The high nickel content gives Inconel its hallmark properties—outstanding resistance to oxidation, corrosion, and creep at elevated temperatures. Some commonly used Inconel grades for casting include: Inconel 625 – Excellent corrosion and fatigue resistance Inconel 718 – High strength and creep resistance up to ~700°C Inconel 713 & 738 – Designed for turbine and high-heat environments These alloys retain mechanical strength where many materials soften or degrade, making them ideal for long-term service in aggressive conditions.
