Cold Rolling

Many different processes are used in the manufacturing of metal parts in cold condition, such as blanking and forming, punching, shearing, cold forging, cold extrusion, powder pressing and cold rolling. Most popular grade for this application is our ASSAB XW-42, being traditional D2-type of material (DIN standard 1.2379, JIS SKD 11). However, ASSAB can offer a plethora of problem solvers depending on identified failure mechanisms.

Rolling are classified using the temperature of the metal rolled. Sheets, strips, bars and rods are examples of cold-rolled products. Generally, cold-rolled workpieces are smaller and higher in strength when compared to hot-rolled. Four high or cluster mills would be needed for cold rolling. Cold rolling, however, cannot reduce thickness of workpiece as much as hot rolling in a single pass.

The choice of the best steel for the forming tools must; not only take the process into consideration, but also the type of metal being formed and the number of parts to be produced. In this case, cold rolling is a method used for forming metal by passing metal stock through one or more pairs of rolls to achieve the required reduction in thickness and yet obtaining uniform thicknesses. A tough tool steel is your solution!

ASSAB XW-42 is a high-carbon tool steel that consists of 12% Chromium. It has high wear resistance and toughness. This type of steel (AISI D2, DIN standard 1.2379, JIS SKD 11) is the most common steel in cold work applications worldwide.

CALMAX

Calmax has high toughness, good wear resistance and good polishability. It is a suitable tool for plastic mould applications. Same chemical composition as Carmo but delivered in soft annealed condition.

CALDIE

Caldie is a medium alloyed tool steel suitable for short and medium run tooling in applications where a combination of very high chipping resistance and compressive strength is required. The property profile makes Caldie a robust cold work tool steel for heavy duty blanking and forming of AHSS (Advanced High Strength Steel).

ASSAB 88

ASSAB 88 is a high alloyed tool steel with a very broad property profile. It is also a very good steel for all types of surface treatments. This combination means that ASSAB 88 is an extremely versatile conventional tool steel for medium run cold work tooling. In markets served by Uddeholm, ASSAB 88 is promoted as Sleipner.

ASSAB PM 23 SUPERCLEAN

ASSAB PM 23 SuperClean is powder high speed steel with excellent wear resistance and toughness. ASSAB PM 23 SuperClean is perfect for high volume cold work applications like blanking of harder materials, e.g. carbon steel or cold rolled strip steel. It is also suitable for forming thinner work materials. In markets served by Uddeholm, ASSAB PM 23 SuperClean is promoted as Vanadis 23 SuperClean.

ASSAB PM 30 SUPERCLEAN

ASSAB PM 30 SuperClean is powder high speed steel meant for cutting tools and other cold work applications. It has excellent wear resistance and toughness.

In markets served by Uddeholm, ASSAB PM 30 SuperClean is promoted as Vanadis 30 SuperClean.

ASSAB PM 60 SUPERCLEAN

ASSAB PM 60 SuperClean is powder high speed steel suitable for cutting tools and other cold work applications. This is a premium steel with extreme wear resistance and high hot hardness. In markets served by Uddeholm, ASSAB PM 60 SuperClean is promoted as Vanadis 60 SuperClean.

VANADIS 4 EXTRA SUPERCLEAN

Vanadis 4 Extra SuperClean is powder tool steel for long run tooling. This is the most versatile PM tool steel on the market today, combining high wear resistance with very good ductility and resistance to chipping of edges. Excellent machinability in both soft and hard condition ensures advantages in both tool making and tool maintenance, where high demands on adhesive wear and chipping resistance are required.

VANADIS 10 SUPERCLEAN

Vanadis 10 SuperClean is a powder tool steel with the highest wear resistance of all the PM tool steel grades, making Vanadis 10 SuperClean suitable for the highest production volumes of abrasive materials. The PM process ensures better chipping resistance than the conventional produced high wear resistant tool steel.

VANCRON SUPERCLEAN

Vancron SuperClean is the most innovative PM tool steel on the market today. Solid state nitriding of the powder particles enables extremely high nitrogen alloy content, giving the tool an "internal surface coating", and the best resistance to galling and adhesive wear. The machinability in hard condition is the best of all the PM grades, ensuring benefits in tool making, as well as tool maintenance.
