40CrMnMo7 vs H13 / X40CrMoV5-1
Side-by-side chemical composition and mechanical property comparison.
Overview
40CrMnMo7
1.2311
Pre-hardened plastic mold steel — delivered at 28-32 HRC, ready for machining without further heat treatment. The European equivalent of AISI P20. Cr-Mn-Mo composition for good through-hardenability in large sections. THE workhorse mold base material for injection molds, compression molds, and die casting dies. Good machinability, polishability, and photo-etchability. Used for mold frames, large injection molds, blow molds, and structural die components.
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.
