摘　　要：针对Cr12模具钢非正常失效现象,研究深冷处理工艺对模具尺寸精度稳定性的作用。Cr12模具钢在深冷处理后,其尺寸精度的稳定性得到大幅度提高。Against the abnormal failure of the die steel of Crl2, influence on the stability of the dimension precision of the die was studied. Its stability of the dimension preci- sion was improved greatly after the die steel of Crl2 being deep-cooling treated.
