摘要
由于301/301L奥氏体不锈钢具有成型性能好、表面质量优良、耐大气腐蚀性能好、成本低等特点,所以越来越广泛地应用在城市轨道客车车体的制造中。但301/301L奥氏体不锈钢在冷弯变形过程存在较大的弹性回复变形,且屈服强度越大,弹性回复就越大。通过对301L奥氏体不锈钢冷弯变形过程中的生产工艺分析,运用合理的变形工艺,解决了变形过程中产生的各种缺陷。
301/301L austenite stainless steel possesses several characteristics with high quality and low cost,such as good forming property,perfect surface quality and good resistance to atmospheric corrosion performance,so it is widely applied to produce rail passenger coach body in cities.But the greater elastic deformation existed in 301/301L austenite stainless steel cold bending course,the bigger yield strength is,the greater elastic recovery is.Through analysis on production process of 301/301L austenite stainless steel cold bending and using reasonable deformation process,it solved all kinds of forming defects occurred in deformation course.
