The proper steel selection for this application depends primarily on powder type, required density of green compact and part geometry. Abrasive wear, cracking and chipping are the most critical failure mechanisms to consider.


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 Caldie
An Electro Slag Remelted (ESR) matrix type cold work tool steel.  It can be hardened to 62 HRC, giving it a very good combination of chipping and cracking resistance, as well as a high compressive strength.  Ideal in situations where higher densities are wanted, or when problems with plastic deformation of the tooling occur.


Vanadis 4 Extra 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 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.

Uddeholm Vancron 40
A high alloyed powder metallurgical tool steel suitable for long run tooling in applications where adhesive wear and galling are the primary failure mechanism.Vancron 40 is developed to be used uncoated and is intended to replace surface treated tooling because of its excellent lubricity.
