The proper tool steel selection for the application depends primarily on the work material type, strength, thickness, and part complexity.
The common and critical failure mechanisms for:
- High strength steels are abrasive wear, chipping/cracking, and Plastic deformation
- Ultra high strength steels are chipping /cracking, abrasive wear, plastic deformation, and galling.
Uddeholm Caldie
A medium alloyed tool steel with an unique properties profile. It 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 over 60 HRC) is necessary.
Bohler K340 Isodur
A high alloyed tool steel suitable for medium run tooling where good resistance to abrasive wear, adhesive wear and chipping resistance is needed. The 8% Cr steel has the ability to be surface treated because of high temperature tempering with achieved hardness of 56-63HRC. K340 is a good alternative to AISI D2 which is chipping / cracking.
Uddeholm Vanadis 4 Extra SuperClean®
Vanadis 4 Extra SuperClean® is a high alloyed powder metallurgical tool steel suitable for long run tooling in applications with high demands on adhesive wear and chipping resistance. Vanadis 4 Extra SuperClean® is the best tool steel for long runs in applications with severe chipping and wear failures. Vanadis 4 Extra is suitable for surface treatments because of high temperature tempering.
Uddeholm Vanadis 6 SuperClean®
A high alloyed powder metallurgical tool steel suitable for long run tooling in applications with high demands on mixed wear (abrasive/ adhesive) or where risk of plastic deformation of the working surface is encountered. Vanadis 6 is suitable for surface treatments because of high temperature tempering.
