[0002] 38CrMoAl is a high-grade nitrided steel with high fatigue strength and strength. It is primarily used for nitrided parts that require precise dimensions after heat treatment, or for various nitrided parts that are not subject to high impact loads but have high wear resistance. These include boring bars, grinding machine spindles, automatic lathe spindles, worms, precision screws, precision gears, high-pressure valves, valve stems, gauges, templates, rollers, dummies, cylinder blocks, compressor piston rods, turbine governors, rotating sleeves, fixed sleeves, and various wear-resistant parts in rubber and plastic extruders. Metal castings typically generate scrap during machining, which requires recycling.
