摘要
高铬镍奥氏体不锈钢与高合金马氏体耐热钢在成分、组织和性能上的差别很大,所以焊接异种钢时会遇到一些特有的问题。对焊后进行热处理及热处理参数进行对比研究,可以为工程实际应用提供参考。
High chromium nickel austenitic stainless steel is very different from high alloy martensite heat resistant steel in composition,structure and performance. So there are some special problems in welding different kinds of steel. The heat treatment and the parameters after welding were compared,which can provide references for practical engineering application.
