Uddeholm Caldie

A ROBUST COLD WORK TOOL STEEL

Uddeholm Caldie is a medium alloyed tool steel suitable for short and medium run tooling in applications where a combination of very high chipping resistance and compressive strength is required. The property profile makes Uddeholm Caldie a robust cold work tool steel for heavy duty blanking and forming of AHSS (Advanced high strength steel).

  • Uddeholm Caldie is very useful for severe cold work applications where there are high demands on both chipping resistance and compressive strength
  • Uddeholm Caldie can easily be surface treated for improved wear resistance
  • Very good dimensional stability
  • 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 Caldie
  • Good flame-, induction- and laser hardenability
  • High toughness and ductility
  • Good wear resistance (adhesive-mixed wear profile)
  • Very suitable for all types of surface treatments
  • Very good polishability, can achieve high surface finish
