What is 713C?

Inconel 713C is a nickel-based precipitation hardening equiaxed cast superalloy mainly used in applications in high temperature environments.

Inconel 713C alloy is known for its excellent high-temperature properties. It can maintain high creep strength, hot and cold fatigue resistance and oxidation resistance in the temperature range below 900°C. The composition of this alloy is relatively simple and does not contain cobalt, so its density is relatively low and it is usually used in the cast state. Specifically, Inconel 713C features include:

Melting point and density: The melting point range is between 1295℃ and 1345℃, and the density is 8.0g/cm³.
Expansion coefficient: In the temperature range from 20℃ to 800℃, its expansion coefficient is 14.7×10^-6℃^-1.
Hardness: The hardness of the cast state at room temperature is HRC33~37.
Mechanical properties: At 20°C, the yield strength is 760Mpa and the elongation is 9.5%; at 800°C, the yield strength is 745Mpa and the elongation is 9.0%.
In addition, Inconel 713C alloy is suitable for manufacturing parts that work at high temperatures, such as turbine rotor blades, guide vanes and integrally cast turbines of gas turbines. Due to its long-term performance at high temperatures, the alloy is also well suited for critical components such as jet engine gas turbine blades.
