H13 steel is a chromium-molybdenum alloy tool steel that conforms to ASTM A681 standards. It can be supplied in round bars, plates, sheets, and squares with diameters up to 400mm, plate thicknesses up to 500mm, and block sizes up to 210x810mm. H13 steel has high hardness and wear resistance making it suitable for hot work tooling applications like dies, molds, and extrusion equipment. It requires heat treatment including annealing, hardening, and tempering to achieve the proper properties for use.

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 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.
