The stainless steels are used more and more in blanking process. To further enhance the quality of blanking fracture surface, this paper made the related experiments of fine-blanking with negative clearance in stainless steel. Through the comparison analysis between the fine-blanking microstructure and common blanking one with stainless steel, the result points out that the fine-blanking with negative clearance inhibit the warping in common blanking, make the work-hardening of material fracture surface improves, and which can have a more positive effect for the fine-blanking with negative clearance. Meanwhile, the work-hardening capacity of two blanking methods was different, and it can enhance the punching section entire strength commendably by fine blanking with negative clearance.
