Chromium hot-work device steels are assigned as gathering H steels as indicated by the AISI classification system. This arrangement of steels begin from H1 to H19. The most usually utilized chromium hot-work steels are H11, H12, and H13, which can be air solidified in 150 mm thick segments. The steels are subjected to insignificant twisting during hardening because of their adjusted alloy content. The tool delivered from chromium hot-work steels can be cooled utilizing water without damage as these steels have low carbon and compound substance.

It contains less vanadium than the broadly utilized H13 hot work tool steel, furthermore the tungsten content gives higher temper resistance.
