\u00a0A viewer in the live stream asked about a continuous punching die for 0.5-thick silicon steel sheets. Since tungsten steel is too expensive, is there a high-speed stee<\/strong>l that can be used as a substitute? The punching speed is 200\u2013300.<\/p>\n\n\n\n

Ever since the price of tungsten steel tripled, mold costs have become unsustainable, leading many to seek a high-speed steel alternative for mold making. Tungsten carbide is a tungsten-cobalt alloy with the highest-quality carbides, offering the best wear resistance. If you need to settle for a second-best option and select a high-speed steel with relatively good wear resistance, powder-metallurgy high-speed steel<\/a><\/strong>\u00a0is definitely the way to go.<\/p>\n\n\n\n

 Powder-metallurgically produced high-speed steel not only has a relatively high carbon content but also a high total alloy content, resulting in an abundance of hard carbides\u2014which are of superior quality. Furthermore, through the advanced powder metallurgy process, its carbides are finely dispersed and uniformly distributed, which greatly enhances wear resistance. Powder-metallurgically produced high-speed stee<\/strong>l offers both high hardness and high strength\u2014properties that ordinary high-speed steel lacks.<\/p>\n\n\n\n

\u00a0For progressive dies with a punching speed of 200\u2013300, punching 0.5-thick silicon steel sheets, and meeting the customer\u2019s requirement to replace tungsten steel\u2014for which there are already successful case studies\u2014I recommend PM23 powder-metallurgical high-speed steel<\/a><\/strong>.<\/p>\n\n\n\n

A customer told me that Yuhui\u2019s PM23 performs exceptionally well when used to punch narrow-edged dies with fine tips. I used to use YG15, but it would either break at the fine tip or snap completely. When punching 0.5-thick silicon steel sheets at a speed of 250 strokes per minute, the PM23 has completed 3 million strokes without ever needing to be resharpened.<\/p>\n\n\n\n

This user\u2019s punching speed is 200\u2013300 strokes per minute when punching 0.5-thick silicon steel sheets. Tungsten carbide is too expensive, so they want to use high-speed steel as a substitute. I think PM23 is a pretty good choice. Not only because there are successful case studies\u2014at a punching speed of 250 strokes per minute, just like theirs, it punched 0.5-thick silicon steel sheets 3 million times without any wear\u2014 This material offers excellent wear resistance, and its price is much lower than that of tungsten carbide. Other cobalt-containing high-speed steels with better wear resistance than PM23 are priced very close to tungsten carbide, so there\u2019s little point in using them as a substitute.<\/p>\n\n\n\n

 I believe that when comparing performance, practical results, and price range, using Yuhui PM23 to replace tungsten carbide for punching 0.5-thick silicon steel sheets offers excellent value for money. Without compromising die life, it also provides the added benefit of better resistance to chipping, while significantly reducing costs\u2014thereby achieving high efficiency, long service life, and low operating costs.<\/p>\n\n\n\n

When recommending mold steel, you should follow this user\u2019s example and tell me the material and thickness of the blank, the mold steel you\u2019re currently using, the problems you hope to solve, the requirements you wish to meet, and even the stamping speed. Only then can I determine what performance characteristics your mold requires and recommend a mold steel grade that matches those requirements, has a proven track record, and meets your needs. Such a recommendation will provide an accurate solution.<\/p>\n\n\n\n
