A netizen asked in the comments section of my video: How can I stamp a 1.8mm-thick 420 steel plate without causing tear marks?<\/p>\n\n\n\n

Scratch marks are typically caused by adhesive wear resulting from stamping debris, which can damage parts or leave scratch marks; this can be avoided by selecting a non-stick die steel<\/strong>.<\/p>\n\n\n\n

\u00a0Speaking of similar stamping conditions, I\u2019m reminded of Mr. Yuan. He was using a die for stamping 2.0-thick stainless steel that combined punching, trimming, and forming into a single operation. With DC53<\/a><\/strong>\u00a0and 8566 steel (four-sided ground), the die required regrinding after every 2,000 products. Without regrinding, there would be significant burrs\u2014over 1.0 in some cases\u2014requiring each product to be polished individually, which was very troublesome. This burr formation was also caused by adhesive wear resulting from material adhesion, though some burrs were due to chipping. However, by using Yuhui 8566 anti-chipping steel<\/strong>,<\/a> the die could withstand 20,000 to 25,000 stamping cycles\u2014a tenfold increase in service life.<\/p>\n\n\n\n

The netizen asked about stamping 1.8mm-thick 420 steel plates. Given the thickness of the material and the fact that 420 stainless steel is a hard grade that is prone to scoring, you might want to try 8566 anti-chipping steel<\/strong> to prevent chipping.<\/p>\n\n\n\n
