Inconel 713 lc is isometric nickel-based precipitation hardening type casting high temperature alloy, is the modification alloy Inconel 713 c, the use of temperature under 900 compared with Inconel 713 c alloy, reduce the carbon content of adjusting the content of chromium and molybdenum alloy has good resistance to creep rupture and cold and hot fatigue resistance, and significantly improve the room temperature plasticity, impact performance and stable organization performance This is of good performance in the application of integral casting turbine has great superiority
In addition, the alloy is not sensitive to the section size and cooling rate of the casting, so it is suitable for casting large castings with a section of more than 130mm
