not just a hardness issue.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.asminternational.org\/materials-resources\/online-databases\/\" target=\"_blank\" rel=\"noopener\">According to ASM Handbook technical references on tool steel behavior, carbide-rich tool steels such as A2 exhibit higher abrasive wear during machining because hard chromium carbides continuously interact with the cutting edge, accelerating flank wear and edge degradation.<\/a><\/p>\n\n\n\n<p>Typical wear modes include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flank wear<\/li>\n\n\n\n<li>Edge
