GH2132 High-Temperature Alloy Round Bar (Fe-Ni-Cr Alloy)
Engineered for aerospace, energy, and industrial applications demanding extreme thermal stability and mechanical strength, GH2132 high-temperature alloy round bar combines a iron-nickel-chromium matrix (Fe-42%, Ni-25%, Cr-15%, Mo-2.5%, Ti-2%) to deliver superior creep resistance, oxidation resistance, and fatigue strength up to 750°C (1,382°F).
