Uddeholm Vanadis 8 SuperClean is especially suitable for very long run tooling where abrasive wear is the dominating problem. Its very good combination of extremely high wear resistance and good toughness also make Uddeholm Vanadis 8 SuperClean an interesting alternative in applications where tooling made of such materials as cemented carbide or high speed steels tends to chip or crack.
Application Examples-
Blanking and forming
Fine blanking
Blanking of electrical sheet
Gasket stamping
Deep drawing
Cold forging
Slitting knives (paper and foil)
Powder pressing
Granulator knives
Extruder screws etc.
FOR GOOD TOOL PERFORMANCE
Correct hardness for the application
Very high wear resistance
Sufficient toughness to prevent premature
failure due to chipping/crack formation
High wear resistance is often associated with low toughness and vice-versa. However, for optimal tool performance both high wear resistance and toughness are essential in many cases.
Uddeholm Vanadis 8 SuperClean is a powder metallurgical cold work tool steel offering a combination of extremely high wear resistance and good toughness.
FOR TOOLMAKING
Machinability
Heat treatment
Dimensional stability in heat treatment
Surface treatment
Toolmaking with highly alloyed steels means that machining and heat treatment are often more of a problem than with the lower alloyed grades. This can, of course, raise the cost of toolmaking.
Due to the very carefully balanced alloying and the powder metallurgical manufacturing route, Uddeholm Vanadis 8 SuperClean has a similar heat treatment procedure to the steel AISI D2. One very big advantage with Udde- holm Vanadis 8 SuperClean is that the dimen- sional stability after hardening and tempering is much better than for the conventionally produced high performance cold work steels. This also means that Uddeholm Vanadis 8 SuperClean is a tool steel which is very suitable for surface coatings.
