GH3128 High-Temperature Alloy Plate (Ni-Cr-W-Mo Alloy)

Engineered for extreme aerospace, gas turbine, and industrial furnace applications, GH3128 high-temperature alloy plate combines a nickel-chromium-tungsten-molybdenum matrix (Ni-75%, Cr-20%, W-2.5%, Mo-2%) to deliver unmatched oxidation resistance, thermal fatigue strength, and creep resistance up to 1100°C (2012°F). Certified to GB/T 14992, AMS 5872, and ASTM B435, this alloy outperforms conventional superalloys like Inconel 600 and Haynes 230, offering 3x the lifespan of 310S stainless steel in cyclic high-temperature environments.
