研究了稀土元素对６０ＣｒＭｎＭｏ热轧辊用钢在其工作温度下拉伸性能的影响，同时对其在５００℃时的疲劳寿命进行了估算．结果表明：加入适量的稀土元素，可以明显提高６０ＣｒＭｎＭｏ钢的延伸率和疲劳寿命。
The effects of rare earth elements on the tensile properties of 60CrMnMo hot-rolled steel at working temperature were studied, and the fatigue life at 500 ℃ was estimated. The results show that adding proper amount of rare earth elements can obviously improve the elongation and fatigue life of 60CrMnMo steel.
