The 8566 anti-chipping steel has tripled punch life\u2014this is the first positive review we\u2019ve received today.<\/p>\n\n\n\n

 Mr. He was stamping 4mm-thick No. 50 steel. The product features sharp corners, and the narrow flange punch\u2014which extends outward\u2014is relatively long, with a width of only 4mm. Previously, he used DC53, which chipped after 10,000 stamping cycles. Now, after switching to Yuhui 8566, he can achieve 32,000 cycles, which is equivalent to a threefold increase in service life.<\/p>\n\n\n\n

 No. 50 steel is a high-carbon steel, which is relatively hard. Combined with the narrow strip, the significant amount of material being punched out, a material thickness of 4mm, and a punch width of 4mm\u2014resulting in a 1:1 punch-to-material ratio\u2014this process combines multiple harsh conditions: hard material, narrow edges, sharp corners, thick plates, and a 1:1 punch-to-material ratio. The working conditions are extremely harsh. Given that the 8566 anti-chipping steel can now withstand 32,000 stamping cycles, I consider this to be an excellent result.<\/p>\n\n\n\n

\u00a0The crack resistance of 8566 is four times that of SKH-9\u00a0high-speed steel<\/a><\/strong> and twice that of D2, with a hardness of HRC 58\u201360. It effectively addresses cracking issues that high-hardness die steels such as D2, DC53, and SKH-9 cannot resolve; 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 ratio is less than 1:1. Chipping issues that standard die steels cannot resolve are all effectively addressed by 8566 anti-chipping steel.<\/p>\n\n\n\n

\u00a0Using\u00a08566 die steel<\/a><\/strong>\u00a0for punch chipping makes a world of difference\u2014it\u2019s like night and day. If your narrow-edge punches are chipping, you should definitely give 8566 anti-chipping steel a try.<\/p>\n\n\n\n
