Inconel713C/K418/K18/518 equiaxed crystal casting superalloy

Overview:

Inconel713C is a nickel-based precipitation hardening equiaxed crystal casting superalloy ( Equivalent to American Inconel713C), with γ' phase as the precipitation strengthening phase, and the use temperature is below 900°C. The alloy has high creep strength, thermal and cold fatigue resistance and oxidation resistance. The alloy has simple composition, does not contain cobalt, and has a low density. It is usually used in the cast state.

Main applications and characteristics of Inconel713C:

This alloy is suitable for making hot-end rotating and static precision castings working below 900°C, such as turbine blades, guide blades, guides and Whole cast turbine, etc. It has been widely used in the production of turbine blades, guide vanes and integrally cast turbines for aviation, ground and marine gas turbines, integrally cast turbine rotors and guides for aerospace missile engines, as well as diesel and gasoline engine booster turbines and hot extrusion dies.

Alloys are treated with hot isostatic pressing (HIP) and subsequent heat treatment, which can improve the plasticity and fatigue resistance of the alloy, and can also restore the structure and use of parts with structural degradation and reduced performance after long-term use. performance. When the alloy is used for a long time under hot corrosion conditions, it must have a protective coating. After long-term aging at 800°C, a small amount of σ phase will precipitate out of the alloy, but it will have no significant impact on its properties.
