GH2132 High-Temperature Alloy Coil (Fe-Ni-Cr Superalloy)

Engineered for aerospace, power generation, and industrial applications requiring exceptional strength and thermal stability, GH2132 alloy coil combines a iron-nickel-chromium matrix (Fe-25%, Ni-35%, Cr-15%, Mo-2%, Ti-2%) to deliver outstanding creep resistance, oxidation resistance, and fatigue strength up to 750°C (1382°F). Certified to GB/T 14992, AMS 5545, and ASTM B670, this alloy outperforms conventional stainless steels and nickel-based superalloys in high-stress, high-temperature environments, offering 2x the lifespan of 316L stainless steel in cyclic thermal applications.
