X153CrMoV12 vs X210Cr12: Both 12% Cr cold work steels — 1.2379 adds Mo+V for improved properties
X153CrMoV12 vs X210Cr12
Side-by-side chemical composition and mechanical property comparison.
Overview
X153CrMoV12
1.2379
High-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.
X210Cr12
1.2080
High-carbon high-chromium cold-work tool steel. Excellent wear resistance and dimensional stability after heat treatment. Used for blanking and forming dies, drawing mandrels, gauges, shear blades, and thread rolling dies. Not suitable for impact loading.

Compatibility Assessment
X153CrMoV12 (D2) adds Mo (0.7%) and V (0.85%) to the 12% Cr base, giving better temper resistance, secondary hardness, and finer carbides than X210Cr12 (1.2080). X210Cr12 is simpler/cheaper with adequate properties for less demanding cold work. Choose D2 for critical stamping dies; 1.2080 for simple gauges/low-stress tooling.
