GH3039 High-Temperature Alloy Coil (Ni-Cr-Mo-Fe Alloy)

Engineered for extreme aerospace, industrial furnace, and energy applications, GH3039 high-temperature alloy coil combines a nickel-chromium-molybdenum-iron matrix (Ni-60%, Cr-22%, Mo-9%, Fe-4%) to deliver unmatched oxidation resistance, thermal fatigue strength, and creep resistance up to 1100°C (2012°F). Certified to GB/T 14992, AMS 5878, and ASTM B435, this alloy outperforms Inconel 601 and Haynes 230 in aggressive thermal and corrosive environments, offering 2x the lifespan of 310S stainless steel while enabling precision forming for critical components.
