Engineering Features of AMS 5391 Inconel 713C: Technical Data Guide
AMS 5391 Inconel 713C (UNS N07713) is a precipitation-hardening nickel-chromium-based cast superalloy designed for high-temperature, high-stress applications up to 1800°F (982°C). It is considered the material of choice for components subjected to extreme thermal stress and oxidation.
What are the properties of Inconel 713C material?
Inconel 713c has a high corrosion resistance. When heated, a thick, stable oxidation layer is formed that protects the surface. The strength of the material is maintained over a wide temperature range. The metal alloy is particularly suitable for applications exposed to high temperatures up to 900°C.
1. AMS 5391 Inconel 713C Chemical Composition
To achieve optimal performance at 1800°F, the ratio of aluminum to titanium is crucial. Our Gnee Alloy factory-supplied master alloy rods ensure zero contamination and precise element control.

4. Inconel 713C Manufacturing and Machining
Heat Treatment: Typically performed in the as-cast state. Optional solution treatment (1175°C/2150°F, 2 hours) followed by stabilization at 925°C/1700°F (1700°F) for 16 hours can improve stress fracture life.
Hot Isostatic Pressing (HIP): Commonly used to eliminate internal porosity.
Machinability: Extremely difficult to machine due to high work hardening. Requires carbide tools, rigid fixtures, and low feed rates.
Weldability: Generally poor. Due to its susceptibility to cracking, it is generally considered unweldable by conventional methods, but repairs can sometimes be achieved through specialized electron beam welding.
6. Typical applications of Inconel 713C alloy
Aerospace: Low-pressure turbine blades, nozzle guide vanes, and integral rotors.
Automotive: Turbine impellers ("hot end") for automotive turbochargers.
Industrial: Gas turbine components for power generation.
Dieting: High-temperature casting and forging dies.

FAQ
Q: Can Inconel 713C be supplied in a wrought (rolled) form?
A: No. Due to its high Al+Ti content, 713C is a cast-only alloy. It is too hard for cold rolling. We provide it as Master Alloy Sticks for vacuum investment casting.
Q: What is the main difference between 713C and 713LC?
A: 713LC (Low Carbon) is designed to improve low-temperature ductility and thermal fatigue resistance, often used in larger turbine components.
Q: Does 713C require post-cast heat treatment?
A: Most 713C components are used in the "as-cast" condition, but a stabilization heat treatment can be performed depending on your specific 1800°F service requirements.
