Stocks H10 Steel in India and abroad. H10 is an amazing high-temperature quality and treating resistance, thermal conductivity and low powerlessness to hot cracking. It can be water cooled to a restricted degree and also suitable for cold hobbling. Utilized for press and penetrating mandrels pass on supplements, massive metal die casting tools.

STEEL PROPERTIES

  • Hot Work Steel H10 is equivalent steel of DIN 2365
  • Great tempering resistance
  • Less susceptible for high hot cracking
  • Excellent thermal conductivity
  • High-temperature durability
  • Can be water-cooled to a constrained degree

APPLICATION

This tool steel is used for hot press and mandrels, press die inserts and forging die, remarkable hot metal die casting tools, die-casting moulds for non-ferrous overwhelming metal pressure die-casting.
