In the aerospace and power generation industries, turbine rotors are core components of engines, operating in some of the world's most demanding environments. At speeds exceeding 100,000 rpm and temperatures reaching 1800°F (982°C), the tolerance for material failure is zero.
As a Tier 1 supplier of high-temperature alloys, Gnee Alloy offers premium Inconel 713C bars specifically designed for these critical components. Our master alloy bars, produced using a vacuum ion melting (VIM) process, possess the metallurgical stability required to push the limits of modern turbine technology.

Super Alloy Inconel 713C Casting Round Rods Buying Guide
Inconel 713C cast round bars are precipitation-hardening nickel-chromium-based superalloys designed for high-temperature, high-stress applications up to 1800°F (980°C), such as gas turbine blades and integral bladed disks. These bars (UNS N07713) exhibit excellent resistance to thermal fatigue and are typically manufactured using vacuum investment casting processes for use in the aerospace and industrial energy sectors.
What are the properties of Inconel 713c material?
Inconel 713c exhibits 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.

FAQ
Q: Why is Inconel 713C preferred over 718 for turbine rotors?
A: While Inconel 718 is a fantastic alloy, it loses significant strength above 1200°F (650°C). For the "hot end" of a turbine, where temperatures reach 1800°F, the Creep Rupture Strength of 713C is far superior, making it the only choice for integral rotors.
Q: How do you ensure batch-to-batch consistency for long-term projects?
A: We utilize standardized VIM melting protocols and ICP-MS testing for every heat. This ensures that the Al/Ti balance remains identical across years of supply, which is critical for maintaining stable casting parameters.
Q: Do you offer annual supply contracts for OEM manufacturers?
A: Yes. We specialize in Annual Supply Contracts that protect our clients from nickel price volatility and ensure a steady flow of premium feedstock for high-volume production.
