Inconel 713LC

Inconel 713LC is a γ' phase precipitation strengthened nickel-based casting superalloy. It has good creep strength, thermal fatigue performance and oxidation resistance below 900℃. The alloy composition is relatively simple, does not contain cobalt, has a low density, and is usually used in the cast state. The use of hot isostatic pressing (HIP) treatment and subsequent heat treatment can improve the plasticity and fatigue properties, and can also restore the structure and performance of parts that have experienced structural degradation and reduced performance after long-term use. A small amount of σ phase will precipitate during long-term aging at 800°C, but it will have no significant impact on performance. The alloy is suitable for making turbine rotor blades, guide vanes, monolithic turbines and other high-temperature parts of gas turbines operating below 900°C.    

This alloy has been widely used as turbine blades, guide vanes and monolithic cast turbines for aviation, ground and offshore gas turbines operating below 900°C. It is also widely used in diesel and gasoline engine booster turbines and hot extrusion dies. Widely used as turbine blades and guide blades for various aero-engines.

Inconel 713LC offers outstanding resistance to thermal fatigue and good castability while offering exceptional rupture strength at 1700°F (927°C). Inconel 713LC is a nickel-chromium alloy that is ideally suited for jet engine gas turbine blades.
