Inconel 713 (Uns N07713) Round Bar For Industrial guide
Inconel 713C (UNS N07713) is a precipitation-hardening nickel-chromium-based cast superalloy bar with excellent creep rupture strength and superior resistance to thermal fatigue at temperatures up to 1700°F (927°C). Round bars made from this material are primarily used in high-temperature, high-stress environments, such as industrial gas turbines and aerospace engineering.
What is INCONEL 713 material?
Inconel 713 is a nickel-based superalloy raw material. This alloy is specifically designed for cast components used in gas turbines and the aerospace industry, and is known for its high strength and oxidation resistance. Inconel 713 operates stably even in the harshest industrial environments.
1. Key Properties of Inconel 713 Round Bars
High Temperature Strength: Excellent fracture strength at temperatures approaching 900°C to 980°C.
Thermal Fatigue Resistance: Excellent resistance to thermal fatigue and oxidation, making it ideal for cyclic temperature applications.
Material Form: Typically supplied in casting form, as it is a cast alloy rather than a forged alloy.
Hardness: Typical range of 33-37 HRC.
