Effect of Quenching Process on Microstructure and Properties of Wear-resistant Steel NM400

    
    Wear-resistant steel NM400 is a special ferrous alloy designed specifically for reducing wear and enhancing performance by increasing hardness. To fulfill these purposes, the steel has to be subjected to a heat treatment process called quenching.
    
    Quenching is a heat treatment process used to harden steel by heating it above the critical temperature, and then cooling it rapidly in oil or water. This process produces a strong and durable steel with improved performance and wear resistance.
    
    The microstructure of steel NM400 can significantly affect its properties, hence it is important to understand the effect of quenching process on microstructure and properties of steel NM400.
