Bohler-Uddeholm UDDEHOLM Caldie Plastic Mold Tool Steel
Categories:	Metal; Ferrous Metal; Tool Steel; Mold Steel
Material Notes:	Description: Uddeholm Caldie is a chromium-molybdenumvanadium alloyed tool steel. Uddeholm Caldie 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
