摘　要: 马氏体不锈钢14Cr17Ni2在轧制过程中产生了表面裂纹,通过对表面裂纹的分析,找出了导致钢材产生裂纹的主要原因。钢中δ铁素体相的含量过高,使钢的塑性变差,在轧制变形过程开裂。通过对14Cr17Ni2钢化学成分的优化和加热温度合理控制,进而减少钢中的δ铁素体含量,钢材表面质量得到明显改善。

Abstract: Martensitic stainless steel 14Cr17Ni2 surface crack appeared in the rolling process,and through the analysis of the surface crack,the main causes of steel crack can be found out. Theδ ferrite content is too high in the steel,so that the plastic deformation of the steel is poor,and the steel body cracks in the process of rolling. Through the optimizing of chemical composition of 14Cr17Ni2 steel,and controlling heating temperature reasonably,the δ ferrite content in the steel degreases,and therefore the surface quality of the steel is improved obviously.
Keywords: 14Cr17Ni2; surface crack; δ ferrite
