In the\u00a0as-quenched condition, A2 can achieve a surface hardness of\u00a060 HRC. As-quenched hardness is influenced by austenitizing temperature. The hardness\u00a0after tempering is 58\u201364 HRC. Tempering at 200\u00b0C (390\u00b0F) can achieve a hardness of 60 HRC.<\/p>\n<h3>Wear Resistance<\/h3>\n<p>The high carbon and chromium content give A2\u00a0excellent wear resistance. Compared to O1 steel, A2 steel has slightly better wear resistance. Compared to A6 steel, its wear resistance is improved by 20-25%. However, its wear resistance is lower than that of D2 steel or high-speed steel.<\/p>\n<h3>Toughness<\/h3>\n<p>A2 steel has\u00a0moderate toughness, higher than oil-hardening die steels and D-series tool steel. Toughness and wear resistance are inversely proportional. The high carbide content in D-series tool steel increases wear resistance but reduces toughness.<\/p>\n<h3>Dimensional Stability<\/h3>\n<p>A2 steel undergoes\u00a0minimal deformation\u00a0during hardening. The\u00a0expansion is approximately 0.001 inches\/inch (0.001 mm\/mm).<\/p>\n<h3>Machinability<\/h3>\n<p>A2 steel is easy to machine after appropriate annealing. If the machinability of tool steel with 1% carbon is set to 100, then the machinability rating of A2 is 65.<\/p>\n<\/section>\n<section class=\"ads2-sec\">\n<h2>Heat Treatment<\/h2>\n<p>A2 is an air-hardening cold work tool steel with good dimensional stability during quenching.<\/p>\n<p>Typical hardening parameters:<\/p>\n<ul>\n<li>Austenitizing: 1775\u20131825\u00b0F (970\u2013995\u00b0C)<\/li>\n\n\n\n<li>Quenching: Air<\/li>\n\n\n\n<li>Recommended: Double tempering<\/li>\n<\/ul>\n<p>Typical working hardness: 58\u201362 HRC<\/p>\n<p>Final hardness depends on section size and tempering temperature.<\/p>\n<\/section>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>A2 tool steel (DIN 1.2363 \/ SKD12) is a stable air-hardening cold work tool steel designed for applications requiring controlled distortion, reliable wear resistance, and good toughness.
