根据有关资料介绍,1Cr13不锈钢具有较高的韧性和冷变形能力,没有回火脆性倾向,有人甚至认为“含Cr13%的钢几乎完全不会变脆,无需考虑此种钢在加工和使用上的困难”。但是,由于热加工不当,1Cr13不锈钢也会出现问题。我厂在加工一批1Cr13不锈钢锻件时,经热处理后,就发现严重脆性,经过多次试验研究,找到了引起脆性的原因,采取措施,消除脆性
According to the information introduced, 1Cr13 stainless steel with high toughness and cold deformation capacity, there is no tendency to temper brittleness, and some even think that “Cr13% of steel almost completely does not become brittle, regardless of such steel in the processing and use difficult”. However, due to improper thermal processing, 1Cr13 stainless steel will also be a problem. When I process a group of 1Cr13 stainless steel forgings, after the heat treatment, we found serious brittleness, after many test and study, found the cause of brittleness, take measures to eliminate brittleness
