18Cr2Ni4WA属于高强度中合金渗碳钢。要使C化物及奥氏体含量不超标可采用渗碳后高温回火900~920℃渗碳，600~650回火，深冷处理，油淬后的硬度也就是48左右，想要达到HRC58-63，必须要进行表面渗碳。
18Cr2Ni4WA钢常用合金渗碳钢,强度，韧性高，淬透性良好，也可在不渗碳而调质的情况下使用，一般用做截面较大，载荷较高且韧性良好，缺口敏感性低的重要零件。18Cr2Ni4WA belongs to high strength medium alloy carburizing steel. To make C materialized and austenite content does not exceed the standard can adopt carburizing after high temperature tempering 900~920 DEG C carburizing, 600-650 tempering, cryogenic treatment, after oil quenching hardness also is 48%, want to achieve HRC58-63, must to the carburizing surface.
18Cr2Ni4WA Steel commonly used alloy carburizing steel, strength, high toughness, quenching of good, also can be in carburization and quenching and tempering, the general use of do larger sections and higher load and good toughness and low notch sensitivity of important parts.18Cr2Ni4WA属于高强度中合金渗碳钢。要使C化物及奥氏体含量不超标可采用渗碳后高温回火900~920℃渗碳，600~650回火，深冷处理，油淬后的硬度也就是48左右，想要达到HRC58-63，必须要进行表面渗碳。
