AISI D6 Tool Steel is a high-carbon, 12% chromium alloy cold work tool steel with tungsten. D6 steel is an air hardening alloy tool steel with excellent resistance to wear and abrasion. As a high carbon high chromium tool steel D6 has better through hardening properties than D3 steel and dimensional stability combined with high resistance to tempering.
We could supply ASTM D6 tool steel and equivalent grade in DIN 1.2436 steel/X210CrW12 steel, JIS SKD2 steel in good quality as per standard requirements.
