A viewer in the livestream asked: \u201cThe hardness of the 05 high-strength steel is 42 degrees, but now, after machining 10,000 pieces, it keeps developing burrs. What kind of die steel<\/strong>\u00a0should I use?\u201d<\/p>\n\n\n\n

 Stamping 0.5mm-thick 65Mn steel sheets with a hardness of 42 HRC involves stamping thin, hard material, which places extremely high demands on wear resistance and the ability to prevent material adhesion. This requires mold steel with high hardness and a high proportion of hard carbide phases\u2014that is, high-carbon, high-alloy mold steel. Currently, the die wears out after only 10,000 stamping cycles. The material used should be cold-work mold steel such as Cr12MoV or DC53; otherwise, it would not wear out so quickly.<\/p>\n\n\n\n

 For stamping 0.5mm-thick, hard 65Mn steel sheets, 8503 die steel offers the best value for money. We have a customer stamping 1 mm thick windshield wiper components, which are also made of hardened 65Mn steel. The customer informed me that 8503 die steel offers the best cost-performance ratio; PM23 can last at most 10,000 cycles, but PM23 powdered high-speed steel costs five times as much as 8503.<\/p>\n\n\n\n

 Mr. Zhang also said: \u201cWe\u2019re now using 8503 die steel for the punches, and they no longer chip at the corners. The results have been good\u2014we\u2019ve stamped 250,000 products without any chipping. We\u2019ve run out of this material, so we need to buy more.\u201d<\/p>\n\n\n\n

Mr. Zhang is stamping 1.0-thick 65Mn steel toothed parts. When he used DC53 for thin-walled, sharp-cornered punches, they chipped quickly. After switching to SKH-9 high-speed steel, the results were still inconsistent\u2014sometimes the punches chipped after 150,000 strokes, and other times after just 2,000 to 3,000 strokes.<\/p>\n\n\n\n

Based on Mr. Zhang\u2019s feedback, when stamping 1.0-thick 65 manganese steel toothed parts, thin-walled, sharp-cornered punches made of SKH-9 would chip after just 20,000\u201330,000 strokes. However, when using 8503 die steel, not only is the price lower, but the punches can withstand 250,000 strokes without chipping\u2014an eightfold increase in service life. This combination of lower cost and eightfold longer service life\u2014offering such excellent value for money\u2014can only be achieved with non-stick 8503 die steel.<\/p>\n\n\n\n

\u00a08503 is a non-stick mold steel exclusive to Yuhui, with a hardness of 55\u201361 HRC and chipping resistance twice that of DC53<\/a>. It offers double the performance without doubling the price, plus the added benefit of non-stick properties. If you\u2019re struggling with punch chipping while stamping thin sheets or hardened thin sheets, you should give 8503 die steel a try\u2014it offers exceptional value for the price.<\/p>\n\n\n\n

Of course, if you still feel that 8503 die steel<\/strong> with a hardness of HRC 59\u201361 is too soft, you can opt for PM23 powdered high-speed steel at five times the price, which has a hardness of HRC 64\u201366. It offers quite good wear resistance, though it is a bit expensive.<\/p>\n\n\n\n
