Side-by-side chemical composition and mechanical property comparison.
Overview
H13 / X40CrMoV5-1
1.2344
The most widely used hot-work tool steel globally. Excellent combination of hot hardness, toughness, and thermal fatigue resistance. Used for die-casting dies (aluminum, zinc, magnesium), forging dies, extrusion tooling, and hot shear blades.
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.
