Product Overview

Hastelloy X nickel-based solid solution strengthened high-temperature alloy, produced by Qinchuan New Materials (Zhengzhou) Co., Ltd., is a high-chromium, high-molybdenum solid solution strengthened nickel-based deformed high-temperature alloy with high iron content. Through the composite solid solution strengthening mechanism of chromium and molybdenum elements, it achieves a balanced match of high-temperature strength, oxidation resistance, and process performance, serving as a general-purpose core heat-resistant material for moderate to high-temperature applications in the aviation, energy, and chemical industries.

Main Product Features

Excellent medium and high temperature performance:Hastelloy X maintains stable tensile strength, yield strength, and anti-creep properties within the core high-temperature range of 600℃ to 900℃, demonstrating excellent high-temperature endurance loading capacity.

Ultimate high-temperature anti-oxidation capability:The alloy surface can form a dense and stable chromium-based oxide protective layer, which is resistant to peeling, flaking, and powdering at high temperatures. It possesses excellent high-temperature anti-oxidation, anti-flue gas sulfidation, and anti-thermal gas erosion properties.

Top-grade process performance:Hastelloy X features mature and stable cold and hot working processes, with excellent forging, rolling, bending, stamping, and deep processing properties. The work hardening is controllable, and the yield rate of finished products is high.

Stable microstructureAfter solution treatment, it exhibits a uniform and stable single-phase austenitic structure, containing only a small amount of TiN and M6C-type carbides, with no harmful precipitate phases.
