Punching 2.5mm-thick stainless steel is heavy-duty stamping on thick, hard material. Other die steels would have chipped to pieces, but Yuhui\u2019s 8566 anti-chipping steel has withstood 100,000 punches without a single issue\u2014that\u2019s absolutely amazing.<\/p>\n\n\n\n

This once again proves that when it comes to preventing punch chipping, using 8566 die stee<\/strong>l<\/a> makes all the difference\u2014it\u2019s like night and day.<\/p>\n\n\n\n

A case study this valuable is definitely worth documenting.<\/p>\n\n\n\n

 8566 is a proprietary anti-chipping mold steel developed by Yuhui, designed primarily to address mold chipping issues. It has been tested across five stamping conditions, six major material types, and seven key industries, with over a thousand successful case studies to date.<\/p>\n\n\n\n

\u00a08566 offers four times the crack resistance of high-speed steel<\/a><\/strong>\u00a0SKH-9 and twice that of D2, with a hardness of HRC 58\u201360. It resolves cracking issues that high-hardness mold steels such as D2, DC53, and SKH-9 cannot address; This is particularly true in harsh conditions such as stainless steel stamping, thick-gauge stamping, fine-blanking dies, sharp-corner stamping, narrow-flange stamping, and applications where the punch diameter is smaller than the sheet thickness or the stamping aspect ratio is less than 1:1. Chipping issues that standard die steels cannot resolve are all successfully addressed using 8566 anti-chipping steel.<\/p>\n\n\n\n

 If your punches are also experiencing chipping issues, you should consider trying 8566 die steel<\/strong>.<\/p>\n\n\n\n
