DescriptionThis alloy is one of the hot work, chromium type tool steels. It also contains molybdenum and vanadium as strengthening agents. The chromium content assists this alloy to resist softening if used at higher temperatures. Secondary hardening steels with good tempering reistance. It maintains high hardness and strength at elevated temperatures. Good resistance to thermal fatigue, erosion and wear. Steel with very high thoughness and good ductilityand hardenability. Tools can be water cooled. ApplicationsH13 finds applications for hot die work, die casting and extrusion dies, wear resisting tools, pressure die casting tools, pressing tools for light and heavy metal. For the highest requirements we recommended UTOPMO2 ESR EFS.

Soft AnnealingHeat to 760-810oC, cool slowly in furnace. This will produce a maximum Brinell hardness of 229.HardeningHarden from a temperature of 1020-1060oC followed by oil, air quenching or warm bath (450-550oC). Hardness after quenching is 52-56 HRC.TemperingTempering temperature: See the diagram bellow.Tempering Temperature (oC) vs. Hardness (HRC) vs. Tensile Stregth (N/mm2)

ForgingHot forming temperature: 1100-900oC. MachinabilityMachinability of H13 is medium to good. It rates as 75 % that of the W group water hardening tool steels which are low alloy and of generally good machinability.Corrosion Resistance This alloy has some corrosion resistance due to its chromium content. However it is still a steel and will rust unless given protective coating.Welding This alloy is weldable. Contact the alloy supplier for information on welding procedures.
