DIN X38CrMoV5-3 1.2367 Tool Steel - Hot Work Steel

X38CrMoV5-3/1.2367 is a chromium-molybdenum-vanadium alloy tool steel widely used in the tool and die industry, conforming to the German standard DIN EN ISO 4957. This material is renowned for its high wear resistance, good hardenability, excellent dimensional stability, and moderate toughness. Following appropriate heat treatment, this steel achieves uniform hardness and stable mechanical properties, making it suitable for applications such as stamping dies in high-wear environments, precision cutting tools, and plastic molding dies.

1.2367 steel contains relatively high proportions of chromium, molybdenum, and vanadium. Chromium significantly enhances the material's hardenability, hardness, and corrosion resistance; molybdenum effectively increases the steel's strength, thermal hardness, and resistance to tempering softening; while the addition of vanadium refines the grain structure, further improving wear resistance and toughness. The synergistic effect of these alloying elements makes this steel grade particularly suitable for demanding applications requiring high wear resistance, high load-bearing capacity, and long-term dimensional stability.
