Material Recommendations

The proper tool steel selection for the application depends primarily on the work material type, strength, thickness, and part complexity.

The most critical failure mechanisms are abrasive wear/adhesive wear, chipping, and cracking.

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.


A high alloyed tool steel with an unique property 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. Caldie is suitable for surface treatments because of high temperature tempering.

A medium alloyed tool steel suitable for short and medium run tooling in applications where a very high chipping resistance is needed. The property profile makes Compax Supreme a robust cold work tool steel for heavy duty blanking and forming.


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.


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.


A high alloyed powder metallurgical tool steel suitable for long run tooling in applications with high demands on abrasive wear resistance or where risk of plastic deformation of the working surface of the tooling is encountered. Vanadis 10 is suitable for surface treatments because of high temperature tempering.
