Hot work tool steels are a group of low carbon steels, known as “H-steels”, used to mainly shape and form materials in manufacturing units that perform at high temperatures of 480 to 760°C (900 to 1400°F), including punching, forging and shearing.
The essential properties of Hot Work Tool Steels are:
- Maintaining their mechanical properties at high temperatures, up to 540°C (1000°F)
- High wear resistance and abrasion at high temperatures
- High thermal conductivity
Such properties are achieved adding alloy elements such as chromium, molybdenum, tungsten, vanadium, nickel and cobalt in varying amounts.
They are further sub-divided as follows:
- H1–H19: chromium content – 5%
- H20–H39: tungsten content – 9-18%; chromium content 3-4%
- H40–H59: molybdenum based
