Principal Design Features
Mold steel H13 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(H13) to resist softening if used at higher temperatures.
Applications
H13 finds applications for hot die work, die casting and extrusion dies.
Machinability
Machinability 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.
Hardness max. 235
