X153CrMoV12
1.2379High-carbon high-chromium ledeburitic cold work tool steel — AISI D2. 12% Cr + 1.5% C forms massive M7C3 carbides giving outstanding wear resistance and cutting edge retention. Air-hardening with minimal distortion. Lower toughness than H13. Used for blanking/stamping dies, thread rolling dies, cold forming tools, slitting cutters, and wear parts. Also popular as high-end knife steel.
