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
