GH3044 High-Temperature Alloy Plate (Ni-Cr-W-Mo Alloy)

Engineered for extreme aerospace, power generation, and industrial heating applications, GH3044 high-temperature alloy plate combines a nickel-chromium-tungsten-molybdenum matrix (Ni-58%, Cr-25%, W-15%, Mo-2%) to deliver exceptional oxidation resistance, thermal fatigue strength, and creep resistance up to 1150°C (2102°F). Certified to GB/T 14992, AMS 5537, and ASTM B435, this alloy outperforms conventional superalloys like Inconel 625 and Haynes 230, offering 3x the lifespan of 310S stainless steel in cyclic high-temperature environments.
