Description
This 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 resistance.
Applications
H13 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.
