Caldie is a matrix tool steel manufactured by Uddeholms AB for cold work applications with high demands on chipping / cracking resistance and compressive strength. Uddeholm Caldie is a robust tool steel and is suitable for medium production volume tooling for blanking and forming difficult production materials such as advanced high strength steel.

Properties
Uddeholm Caldie is a chromium-molybdenumvanadium alloyed tool steel which is characterized by:
Application areas
Uddeholm Caldie is suitable for short to medium run tooling where chipping and/or cracking are the predominant failure mechanisms and where a high compressive strength (hardness of over 60 HRC) is necessary. This makes Uddeholm Caldie very suitable for severe cold work applications where the combination of a hardness above 60 HRC and a high cracking resistance is of utmost importance e.g. as in the blanking and forming of ultra high strength steel sheets. Uddeholm Caldie is also very suitable as a substrate steel for applications where surface coatings are desirable or necessary.
Cold Work applications
Engineering components and machine parts
This steel can be used in engineering applications where high compressive strength has to be combined with high ductility/toughness. Knives for fragmentation of plastics and metals and roll forming rolls are good examples
