Inconel 718 Round Bar Stock

---

Inconel 718 alloy round bar is a nickel-based high-temperature alloy precipitated and strengthened by body-centered square γ" and face-centered cubic γ' phases. It has good comprehensive properties in the temperature range of -253~700°C, and the yield strength is below 650°C. It ranks first among deformed high-temperature alloys and has good fatigue resistance, radiation resistance, oxidation resistance, corrosion resistance, as well as good processing performance, welding performance and long-term structural stability. It can manufacture various parts with complex shapes and is used in aerospace. , nuclear energy, and petroleum industries, it has been widely used in the above temperature range.
