Bohler-Uddeholm UDDEHOLM Caldie Plastic Mold Tool Steel

Description: Uddeholm Caldie is a chromium-molybdenumvanadium alloyed tool steel.Uddeholm Caldie which is characterized by:Very good chipping and cracking resistanceGood wear resistanceHigh hardness (>60 HRC) after high temperature temperingGood dimensional stability in heat treatment and in serviceExcellent through-hardening propertiesGood machinability and grindabilityExcellent polishabilityGood surface treatment propertiesGood resistance to tempering backVery good WEDM propertiesApplications: 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 necessaryCold Work Applications:Blanking applications where high ductility and toughness are needed to prevent chipping/crackingCold forging and forming operations where a high compressive strength combined with good resistance to chipping/cracking are necessaryMachine knivesThread rolling diesSubstrate for surface coatings
