Influence of Mo on Continuous Cooling Transformation of 09CuPCrNi Anti-weathering Steel

Chunling Zhang

Abstract

CCT diagrams and microstructure of 09CuPCrNi steels were investigated using dilatometric method and optical microscopy respectively.Compared with that of the CCT diagram of the conventional 09CuPCrNi steel,the transformation range of bainite is partly separated from that of ferrite when the adding amount of Mo is 0.33%wt,and they are completely separated when the amount of Mo is 0.41%wt,also the transformation ranges of pearlite and bainite are separated completely.
