Hot Work Tool Steel

Features of Hot Work Tool Steel

• 1 Our hot work tool steel is a uniquely processed group of steel used to shape and cut other materials at high temperature. Classified with the ‘H’ prefix, ‘H-group’ steels undergo intense processing to allow them to retain strength and hardness whilst being used in high temperature conditions.
  The characteristic hardness and resistance of our hot work tool steel is due to high level of carbide, moderate level of alloy and low level of carbon.
   
  Our H1–H19 steels contain approx. 5% chromium, H20–H39 contain approx. 10-18% tungsten and 3-4% chromium, and our H40–H59 steels are based on molybdenum.
  AISI H13 steel consists of chromium, molybdenum and vanadium and is known for its high hardenability and great toughness.
  The molybdenum and vanadium act as strengthening agents while the chromium content helps the AISI H13 tool steel to withstand softening when used at high temperatures. It also combines shock and abrasion resistance, has good red hardness, can resist rapid cooling and withstand premature heat checking. The H13 tool steel has good machinability, good weldability and good ductility and it can be formed by conventional means.   So H13 steel applications is very range in hot forged mold, hot work tool.
