1: H10 steel introduction
H10 tool steel is one hot works tool steel in ASTM A681 standard, which is for alloy tool steel. The ASTM/AISI classifies chromium hot work tool steels as group H steels, ranging from H10, H11, h12 to H19. AISI H10 Tool Steel is one of chromium hot-work tool steel that exhibits excellent resistance to softening at elevated temperature.
H10 Tool Steel is capable of being heat treated to higher hardness than the tungsten hot work steels, and in addition offers greater toughness. H10 tool steel has good thermal fatigue characteristics, and unlike the tungsten hot work steels and H10 hot work tool steels may be safely water cooled in service.
