There are different processes used for the production of metal tools under ‘cold condition’, which is broadly defined as surface temperatures below 200°C. These processes include blanking, drawing, cold extrusion, fine blanking, cold forging, cold forming, powder compacting, cold rolling, and shearing (industrial knives). The choice of the best steel for the forming and blanking tools must not only take the process into consideration but also the type of metal being formed or blanked.
Our product programme for cold work steel comprises different combinations of resistance to abrasive and adhesive wear, plastic deformation, chipping and cracking, machinability and grindability, and heat treatment properties.
The cold work grades below are generally available from stock. The sheets for each grade are available for purchase.
