Composition limits of H-13 based on the AISI/ H-13, which leads to a UNS (T20813) standards are (mass %): C, Mn, Si, Cr, greater dispersion of vanadium carbides Fe max Ni, Mo, V, max Cu, and higher wear max P, and max S. Where specified, as resistance. The H-13. Cr resulfurized H-13, sulfur may be increased to steel also has a slightly to improve machinability. wider range of the Mo Besides the standard H-13 grade, various modified, other principal premium, and superior grades of H-13 are alloying elements, V. available from hot work steel producers, usually allowing producers with limiting phosphorus and/or sulfur levels flexibility in tailoring C. that are below the standard Composition limits mechanical properties to improve toughness and thermal fatigue for given heat resistance and containing principle alloying treatments and applications.

acceptance for hot work dies and tooling differ depending on the industry. 1.4.1 [Table] Standard AISI/UNS chemical composition of H-13 steel and typical compositions of specially produced commercial grades of H-13
