Among the core components of a gas turbine, the nozzle guide vanes (NGV) and turbine blades are the first line of defense against airflow temperatures reaching 1800°F (982°C). In these critical "hot-end" components, even minute geometric changes can lead to aerodynamic losses or mechanical interference.
Inconel 713C (UNS N07713) is the industry's most reliable component solution, combining high-temperature strength with exceptional dimensional stability. Gnee Alloy, your one-stop shop for high-temperature alloy sourcing, provides high-purity master alloy bars required to power next-generation gas turbines.

Inconel 713C Bar Guide for High-Temperature Nozzles and Turbine Blades
Inconel 713C is a nickel-based superalloy bar designed for exceptional creep rupture strength at temperatures up to 982°C (1700°F–1800°F), making it an ideal material for manufacturing turbine blades, nozzles, and turbochargers. It exhibits excellent thermal fatigue resistance and oxidation resistance, but due to its high hot brittleness, it is primarily used in cast form.
What are the differences between Inconel 718 and 713C?
Inconel 713C is a precipitation-hardening nickel-chromium alloy. Inconel 718 is an age-hardening nickel-chromium alloy. Inconel 713C has superior mechanical properties at high temperatures compared to Inconel 718. Inconel 713C also has better corrosion resistance than Inconel 718.
Inconel 713C bars are a nickel-based superalloy designed for high-temperature applications, such as gas turbine blades and nozzles. Inconel 713C is renowned for its exceptional oxidation resistance and thermal fatigue resistance, and is widely used in industries with extremely high performance requirements. These alloy bars are available in 80*700mm, 80*780mm, and 80*880mm sizes, maintaining excellent strength and durability even under extreme conditions.

FAQ
Q: Why is Inconel 713C preferred for nozzles over Hastelloy X?
A: While Hastelloy X is easier to weld, Inconel 713C has much higher creep rupture strength. For nozzles that must withstand gas pressure and high heat without warping, 713C offers far superior dimensional stability.
Q: Can your bars be used for integral rotors?
A: Yes. Our high-purity VIM-melted feedstock ensures the metallurgical integrity required for the high RPMs of integral turbine rotors used in APUs and small jet engines.
Q: What is your standard lead time for wholesale orders?
A: As a one-stop procurement hub, we maintain a strategic stock of AMS 5391 master alloys. Standard bars can be shipped within 2-3 weeks via our global logistics network.
