特性
播报编辑中加入Cr、Mn、Mo元素主要是提高钢的淬透性，尤其是共同作用时，淬透性提高极大。Cr、Mn、Mo元素可固溶于铁素体中起固溶强化作用，又可固溶于Fe3C中形成（Fe、Cr、Mo）3C，改善其硬度，提高钢的耐磨性。Cr、Mn、Mo元素共同作用显著提高钢的回火稳定性。Mo元素可减少回火脆性和细化晶粒。由于Ni元素显著提高钢的淬透性、韧性与耐热疲劳性能，所以钢与5CrNiMo钢相比，虽然强度不降低，但常温及较高温度下的韧性和塑性却降低很多，且淬透性和耐热疲劳性能也稍低。 另外，钢中加入Mn、Mo元素，钢的过热敏感性稍大。此外，钢中存在Cr元素使钢产生一定的抗氧化性与耐蚀性。

热处理
播报编辑热处理规范：淬火,820～850℃油冷。回火用途 加热温度/℃ 加热介质 硬度（HRC）消除应力，稳定组织和尺寸钢的热加工工艺示于下表。项目加热温度/℃开始温度/℃终止温度/℃冷 却钢锭钢坯1140～11801100～11501100～11501050～1100850～800850～800缓冷（坑或砂冷）缓冷（坑或砂冷）注：钢锻后，应进行缓冷。大型模具在锻造后，需放在热至600℃的炉中保温，待整个模具内外温度一致后，再炉冷至150～200℃，然后取出空冷。
