Due to the use of advanced powder metallurgy technology, segregation defects have been eliminated, and the steel has no directionality. No matter how it is used, it does not affect its performance, while improving its resistance to cracking.<\/p>\n\n\n\n<p>&nbsp;And it has a high hardness of 64-66HRC, tungsten W content of 6.0%, vanadium V content of 3.0%, high hardness, high alloy, advanced powder smelting process, achieving high wear resistance, anti cracking performance and wear resistance, about 2-3 times that of ordinary cast high-speed steel SKH51.<\/p>\n\n\n\n<p>&nbsp;I recommend PM23 for any quenched hard material that has undergone stamping heat treatment. It has both high hardness and strength, which means it is both crack resistant and wear-resistant, and the punch life is guaranteed. Both stainless steel hard materials and 65 manganese steel quenched hard materials have a large number of successful case experiences.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0Hello boss, may I ask what\u00a0die steel\u00a0is used for 420J2 stainless steel with a hardness of 48-50 degrees after punching, shearing, and heat treatment, with a thickness within 1.0? &nbsp;Stamping 1mm 420J2 hard material with a material hardness of 48-50HRC is a typical thick plate hard material stamping, which is prone to breakage and wear, [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-295","post","type-post","status-publish","format-standard","hentry","category-blog"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/posts\/295","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=295"}],"version-history":[{"count":1,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/posts\/295\/revisions"}],"predecessor-version":[{"id":297,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=\/wp\/v2\/posts\/295\/revisions\/297"}],"wp:attachment":[{"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=295"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=295"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.wudejiansteel.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=295"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
