In the demanding fields of aerospace and industrial gas turbines, metallurgical integrity is the dividing line between peak performance and catastrophic failure. Whether your project adheres to the US UNS N07713 standard or the European DIN 2.4671 standard, the requirement remains consistent: the engine's "hot end" must possess extremely high creep rupture strength.
As a Tier 1 superalloy supplier, Gnee Alloy's VIM melt master alloy bars not only meet but exceed the stringent AMS 5391 standard. Our factory-direct sales model ensures that foundries worldwide can obtain Tier 1 quality products at highly competitive wholesale prices.

Inconel 713C (UNS N07713/DIN 2.4671) Alloy: Technical Data Sheet and Wholesale Sourcing Guide
Inconel 713C (UNS N07713 / DIN 2.4671) is a precipitation-hardening nickel-chromium-based cast superalloy with excellent structural stability and high creep rupture strength, especially in the temperature range of 700°C to 1000°C. Due to its excellent oxidation resistance and thermal fatigue resistance, Inconel 713C is widely used in critical thermal channel components of aerospace and industrial gas turbines.
What are the properties of Inconel 713C material?
Inconel 713C has extremely high corrosion resistance. Upon heating, a thick, stable oxide layer forms on the surface, providing protection. This material maintains its strength over a wide temperature range. This metal alloy is particularly suitable for applications with temperatures up to 900°C.
