Caldie

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.

• Blanking applications where high ductility and toughness are needed to prevent chipping/cracking
• Cold forging and forming operations where a high compressive strength combined with good resistance to chipping/cracking are necessary
• Machine knives
• Thread rolling dies
• Substrate for surface coatings

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
