Uddeholm Calmax

A ROBUST COLD WORK TOOL STEEL FOR HEAVY DUTY BLANKING AND FORMING

Uddeholm Calmax is a medium alloyed tool steel suitable for short and medium run tooling in applications where a very high chipping resistance is required. The property profile makes Uddeholm Calmax a robust cold work tool steel for heavy duty blanking and forming.
  • Uddeholm Calmax is very useful for severe cold work applications where there are very high demands on chipping resistance
  • Reduced maintenance and downtime costs combined with increased productivity due to the reduced likelihood of premature failures
  • Reduced maintenance and downtime costs combined with increased productivity due to simplified maintenance procedures
  • Good weldability and the availability of welding electrodes with the same chemical composition as Uddeholm Calmax
  • Good flame-, induction- and laser hardenability
  • High toughness and ductility
  • Good wear resistance (adhesive-mixed wear profile)
  • Good through hardening properties
  • Good stability in hardening
  • Good weldability
  • Good flame-, induction- and laser hardenability
