AMS 5391 Inconel 713C round bar manufacturer
AMS 5391 Inconel 713C is a precipitation-hardening nickel-chromium vacuum-cast superalloy (UNS N07713) specifically designed for high-temperature strength, particularly suitable for jet engine turbine blades and turbochargers. Bars, rods, and billets are used to manufacture components requiring ultra-high fracture strength up to 1700°F (925°C) and excellent resistance to thermal fatigue.
What are the properties of Inconel 713 material?
Inconel 713LC alloy is a high-performance nickel-based alloy with excellent high-temperature performance, oxidation resistance, creep resistance, and corrosion resistance. These properties make it widely used in high-temperature and corrosive environments such as aerospace, petrochemical, and nuclear energy.

FAQ
Q: How do you verify the ppb-level trace element content?
A: We utilize high-sensitivity ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and OES testing. Our internal lab is calibrated against international standards to ensure that every MTC 3.1 certified report is 100% accurate.
Q: Can your Inconel 713C bars help reduce our foundry's scrap rate?
A: Absolutely. Most casting cracks are caused by non-metallic inclusions or harmful trace elements. By using our ultra-low gas content and high-purity master alloy, you reduce the source of these defects, directly increasing your bottom-line profit.
Q: Do you offer wholesale pricing for smaller foundries?
A: Yes. While we handle Annual Supply Contracts for major OEMs, we also support smaller boutique foundries with competitive wholesale pricing for pallet-sized orders.
