关于铁素体不锈钢焊接晶间腐蚀的若干问题

On Some Problems for Ferritic Stainless Steel Grain Boundary Corrosion During Welding

关于铁素体不锈钢焊接晶间腐蚀的问题，目前尚缺少统一的看法和系统的资料。本文对铁素体不锈用焊接晶间腐蚀的现象；铁素体不锈钢的敏化；铁素体不锈钢晶间腐蚀的有关理论；钢的化学成分和腐蚀介质的影响；以及对焊接时的注意事项等问题进行了深入论述。

There are not yet a common view and sysmatical data on the problems of the grain boundary corrosion during welding ferritic staiuless steel at present. This article deeply discusses the phenomenon of ferritic stainless steel grain boundary corrosion,the sensitization of ferritic stainless steel,the theories on the grain boundary corrosion,the affections of elemental compositions and corrosion mediums,and attention points in welding.
