H21 Steel

H21 Steel is a hot work tool steel for oil or air solidifying to grow high hot quality, maintenance of hardness, and warmth checking resistance.

This is mostly utilized as hot work devices, instruments for manufacture of hollows, screws, rivets, nuts and bolts. Die casting tools, forming dies, die inserts, hot shear blades.

Hot work steel with good toughness include tungsten Chromium Carbon Vanadium usually is working hardness is 40.0 to 55.0 HRC size available in round, flat and square.

Applications for H21 steel

The H21 tungsten hot-work tool steels are mainly used for hot-working dies and toolings like
