Uddeholm Dievar


Uddeholm Dievar is a premium steel developed for the demanding application of high pressure casting. It is the industry benchmark for a high performance steel for the longest tool life and lowest crack risks due to its superior toughness and ductility. Apart from die casting it has proven itself as a great tool steel for other applications such as forging, extrusion and hot stamping.
  • The steel has a very good resistance to heat checking, gross cracking
  • Excellent toughness and ductility in all directions
  • Good temper resistance
  • Good high-temperature strength
  • Excellent hardenability
  • Good dimensional stability throughout heat treatment and coating operations
