High Temperature Alloy Plate (Inconel®, Hastelloy®, Haynes®, etc.)
Engineered for industries operating in extreme thermal and corrosive environments, our high-temperature alloy plates deliver unmatched performance in aerospace, power generation, and chemical processing. Made from nickel-chromium-molybdenum superalloys (e.g., Inconel 718: Ni-52.5%, Cr-19%, Mo-3%), these plates withstand temperatures up to 1,200°C (2,192°F) while resisting oxidation, sulfidation, and creep deformation. Certified to AMS 5599, ASTM B168, and ASME SB168, they outperform conventional stainless steel with 10x longer lifespan in aggressive conditions.
