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.
AISI A2
A medium alloyed tool steel suitable for short and medium run tooling applications where a combination of chipping resistance, wear resistance and hardness are needed.
AISI O1
A low alloyed, all-purpose cold work tool steel with very good machinability. It is suitable for short run tooling for a wide variety of cold work applications. As this is an oil-hardening grade it should only be used for smaller tools (wall thickness less than 50 mm).
AISI D2
A high alloyed tool steel suitable for medium run tooling in applications where a good resistance to abrasive wear is generally needed. The 12-% chromium steel is the most common tool steel type used for cold work tooling.
AISI S7MQ
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 S7MQ a robust cold work tool steel for heavy duty blanking and forming.
Uddeholm Caldie
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.
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.
Uddeholm Vanadis 10 SuperClean®
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.
