Why use DIEVAR steel for die molds?

Dievar steel is a specially developed steel grade by Uddeholm. This specialty steel was developed to provide the best possible performance. Chemical composition and cutting edge production technique make the Dievar property profile outstanding. A combination of excellent surface toughness and hot strength versatility give Swedish Dievar Steel a very good heat checking- and gross cracking resistance. This special steel is ideal hot work applications such as die casting and extrusions.

Swedish Dievar Steel Properties

Dievar allows for very significant enhancements in die life; which results in a producing the tool economically with maintenance cost savings. Dievar is a high performance chromium-molybdenum-vanadium alloyed hot work tool steel which offers a very good resistance to heat checking, gross cracking, hot wear and plastic deformation. This special steel grade is characterized by:

  • Excellent toughness and ductility in all directions
  • Good temper resistance
  • Good high-temperature strength
  • Excellent harden ability
  • Good dimensional stability throughout heat treatment and coating operations
