38CrMoAlA hot rolled nitriding alloy steel round bar
38CrMoAl is a high-quality nitrided alloy steel known for its excellent wear resistance, high fatigue strength, and superior surface hardness after nitriding treatment. It features low thermal expansion coefficient and good creep resistance. This material is primarily used for precision components requiring high dimensional stability and wear resistance under low impact loads, such as spindles, molds, and high-pressure valves.
