38CrMoAlA is a high-grade nitriding steel, executed according to the standard: GB/T3077-2015. 38CrMoAlA has high surface hardness, wear resistance and fatigue strength, as well as good heat resistance and corrosion resistance, but its hardenability is not high. It is mainly used for nitrided parts with precise dimensions after heat treatment, or various nitrided parts with high wear resistance but not subjected to large impact loads, such as boring bars, grinding machine spindles, automatic lathe spindles, worms, precision lead screws, precision gears, high-pressure valves, valve stems, gauges, templates, rollers, dies, cylinder blocks, compressor piston rods, speed governors, rotating sleeves and fixed sleeves on steam turbines, various wear-resistant parts on rubber and plastic extruders, etc.
