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. Physical properties (avarage values) at ambient temperatureModulus of elasticity [103 x N/mm2]: 215 Density [g/cm3]: 7.78Thermal conductivity [W/m.K]: 25.0 Electric resistivity [Ohm mm2/m]: 0.52Specific heat capacity[J/g.K]: 0.46Thermal conductivity [W/m.K]M
