D2 \uacf5\uad6c\uac15<\/a> is a high-carbon, high-chromium, air-hardening cold-work tool steel. Its typical composition contains 1.40\u20131.60% carbon and 11.00\u201313.00% chromium, with molybdenum and vanadium added to improve hardenability, wear resistance, tempering stability, and dimensional control during heat treatment.<\/p>\n\n\n\n

Chemical Composition of D2 Tool Steel D2 tool steel is a high-carbon, high-chromium, air-hardening cold-work tool steel. Its typical composition contains 1.40\u20131.60% carbon and 11.00\u201313.00% chromium, with molybdenum and vanadium added to improve hardenability, wear resistance, tempering stability, and dimensional control during heat treatment.
