Uddeholm Caldie is a chromium-molybdenum-vanadium alloyed tool steel which is characterized by:

• Very good chipping and cracking resistance

• Good wear resistance

• High hardness (>60 HRC) after high temperature tempering

• Good dimensional stability in heat treatment and in service

• Excellent through-hardening properties

• Good machinability and grindability

• Excellent polishability

• Good surface treatment properties

• Good resistance to tempering back

• Very good WEDM properties

Applications
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 an excellent problem solver 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

• 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

UDDEHOLM COMPONENT BUSINESS APPLICATIONS
Uddeholm Caldie 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.
