.... The tungsten-base, hot-work die steels contain 9 to 18% W, 2 to 12% Cr, and sometimes small amounts of vanadium. The high tungsten content provides resistance to softening at high temperatures while maintaining adequate toughness, but it also makes water cooling of these steels impossible. Low-alloy...

..., these steels are tempered at relatively low temperatures, for example, die holders for hot forging or hammer die blocks. Low-alloy steels with higher (2 to 4%) nickel contents, with ASM designations 6F5 and 6F7, have higher hardenability and toughness and can be used in more severe applications than steels 6G...

.... Chromium hot-work steels (types H10 to H19) have good resistance to heat softening because of their medium chromium content and the addition of carbide-forming elements such as molybdenum, tungsten, and vanadium.
