摘　　要：为减少12%Cr马氏体铁素体型不锈钢因晶粒粗大,造成冲击功不合现象。通过对比国内外标准推荐热处理制度,并对1Cr12Mo进行淬火工艺试验,试验结果表明:(1)1Cr12,1Cr13,2Cr13以及1Cr11MoV的淬火温度较高;(2)淬火温度过高导致12%Cr钢晶粒粗大,粗晶降低材料的冲击性能;(3)12%Cr钢的淬火温度应该降到980±10℃。In order to reduce the phenomenon of 12% Cr steel appear coarse grains result in mechanical property is unqualified. The effect of quenching temperature on impact properties of 1Crl2Mo steel was studied experimentally in this paper. The results show that ： the quenching temperature of 1Cr12,1Cr13,2Cr13 and 1Cr11MoV steel are higher in coarse grains. The coarse grains reduce the impact of 12% Cr steel. The optimum quenching temperature of 12% Cr steel is 980± 10℃.
