Chemical Elements and Performance Meaning<\/h1>\n        <p><a href=\"https:\/\/aobosteel.com\/a2-tool-steel\/\">A2 tool steel<\/a> is an <a href=\"https:\/\/aobosteel.com\/air-hardening-tool-steel\/\">air-hardening cold-work tool steel<\/a> with about 0.95\u20131.05% carbon, 4.75\u20135.50% chromium, 0.90\u20131.40% molybdenum, and a small amount of vanadium. This composition gives A2 useful wear resistance, good toughness, deep <a href=\"https:\/\/aobosteel.com\/tool-steel-hardenability-chart\/\">hardenability<\/a>, and low heat-treatment distortion.<\/p>\n      <\/div>\n      <div class=\"ts-tool-area\">\n        <p class=\"ts-p\">This makes A2 suitable for cold-work tools that need both edge strength and <a href=\"https:\/\/aobosteel.com\/tool-steel-size-change-in-heat-treatment\/\">dimensional stability<\/a>, such as blanking dies, forming dies, punches, shear blades, slitting knives, and precision tooling.<\/p>\n        <h2 class=\"ts-h2\" id=\"h-a2-tool-steel-chemical-composition-table\">A2 Tool Steel Chemical Composition Table<\/h2>\n        <p class=\"ts-p\">A2 belongs to the AISI A-series air-hardening tool steels. Its composition features a medium alloy content rather than extreme carbon or chromium levels.<\/p>\n        <div class=\"ts-table-wrap\"><table class=\"ts-table\">\n            <thead>\n              <tr><th>Element<\/th><th>Typical Range<\/th><th class=\"ds-text\">Main Function<\/th><th class=\"ds-text\">Practical Meaning<\/th><\/tr>\n            <\/thead>\n            <tbody>\n            <tr><td class=\"ts-grade\"><a href=\"https:\/\/aobosteel.com\/tool-steel-composition-chart\/\">Carbon, C<\/a><\/td><td class=\"ts-num\">0.95\u20131.05%<\/td><td class=\"ts-long ds-text\">Builds hardness and carbide structure<\/td><td class=\"ts-long ds-text\">Gives A2 wear resistance after hardening<\/td><\/tr>\n            <tr><td class=\"ts-grade\">Chromium, Cr<\/td><td class=\"ts-num\">4.75\u20135.50%<\/td><td class=\"ts-long ds-text\">Improves hardenability and forms carbides<\/td><td class=\"ts-long ds-text\">Allows air hardening and improves abrasion resistance<\/td><\/tr>\n            <tr><td class=\"ts-grade\">Molybdenum, Mo<\/td><td class=\"ts-num\">0.90\u20131.40%<\/td><td class=\"ts-long ds-text\">Improves hardenability and temper resistance<\/td><td class=\"ts-long ds-text\">Helps A2 harden deeper and keep hardness after tempering<\/td><\/tr>\n            <tr><td class=\"ts-grade\">Vanadium, V<\/td><td class=\"ts-num\">0.15\u20130.50%<\/td><td class=\"ts-long ds-text\">Refines grain size and forms fine carbides<\/td><td class=\"ts-long ds-text\">Improves edge stability and toughness control<\/td><\/tr>\n            <tr><td class=\"ts-grade\">Manganese, Mn<\/td><td class=\"ts-num\">Up to 1.00%<\/td><td class=\"ts-long ds-text\">Supports hardenability and steelmaking quality<\/td><td class=\"ts-long ds-text\">Helps A2 harden more uniformly<\/td><\/tr>\n            <tr><td class=\"ts-grade\">Silicon, Si<\/td><td class=\"ts-num\">Up to 0.50%<\/td><td class=\"ts-long ds-text\">Deoxidizes and mildly strengthens the steel<\/td><td class=\"ts-long ds-text\">Supports clean steel and matrix strength<\/td><\/tr>\n            <\/tbody>\n          <\/table>\n        <\/div>\n        <p class=\"ts-p\">The most important point is the relationship between carbon, chromium, and molybdenum.

It is not the best grade for every failure mode. If <a href=\"https:\/\/aobosteel.com\/abrasive-wear-resistant-tool-steels\/\">severe abrasion<\/a> is the main problem, D2 may be better.
