A viewer in the live stream asked: When stamping 0.03-thick stainless steel with a progressive die, what materials can be used as alternatives to tungsten carbide?<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

 Stamping 0.03-thick stainless steel is considered thin-gauge stamping. Dies for this application generally do not chip, so the primary consideration is wear resistance. Since the stamping speed is set very high, red hardness must also be taken into account. Tungsten carbide is, of course, the best choice\u2014it is a tungsten-cobalt alloy that offers high hardness, excellent wear resistance, and superior red hardness. When used for stamping 0.03-thick stainless steel, it is undoubtedly highly wear-resistant. However, following this year\u2019s threefold increase in the price of tungsten carbide, if you prefer not to use it and instead wish to substitute it with a mold steel that offers comparable wear resistance, powder-metallurgically produced high-speed steel with high cobalt, tungsten, and vanadium content is the ideal alternative. Currently, there are three options available.<\/p>\n\n\n\n

\u00a0The first is PM60\u00a0powder-metallurgic high-speed<\/strong><\/a> steel, with a carbon content of 2.3%, cobalt content of 10.8%, and vanadium content of 6%. It has a hardness of 67\u201369 HRC. Thanks to the advanced powder metallurgy process, its carbides are finely and uniformly dispersed. With a high density of carbides and excellent distribution, it offers outstanding wear resistance and red hardness. When used for high-speed punching of 0.03-thick stainless steel, its wear resistance is undoubtedly excellent.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

 The second grade is T15, a tungsten-based high-carbon, high-vanadium, cobalt-containing high-speed steel with 12% tungsten, 5.0% cobalt (Co), and 5.0% vanadium (V). With its high alloy content, it offers excellent wear resistance. It is reportedly designed specifically for punching stainless steel; due to its high tungsten content, it also exhibits good red hardness and very good wear resistance.<\/p>\n\n\n\n

 The third option is undoubtedly S390, with a tungsten content of 10.5%, cobalt (Co) content of 8.0%, and vanadium (V) content of 5.0%. It has a hardness of HRC 65\u201369. With its very high alloy content and high hardness, it offers excellent wear resistance.<\/p>\n\n\n\n

 The user asked about high-speed stamping of 0.03 stainless steel using continuous dies and does not want to use cemented carbide (tungsten steel). In that case, the only options are PM60, T15, S390, These three materials can serve as alternatives to tungsten carbide. Other mold steels lack sufficient wear resistance\u2014at the very least, they have insufficient total alloy content and an inadequate variety of carbides. As for the morphology, particle size, and distribution of the carbides, there\u2019s no need to even consider them\u2014none of them compare to these three mold steels.<\/p>\n\n\n\n

 When deciding which die steel to choose, you\u2019ll need to comprehensively consider a range of factors, including your mold\u2019s operating conditions, any requirements for toughness, and the ease of procurement.<\/p>\n\n\n\n
