The High Carbon Cold Rolled Steel group consists of steel products created by applying heat treatment to cold-rolled and annealed dry steels. Users shape the strip or coil material in its dry spring steel form and then apply heat treatment to increase its hardness, transforming the material into the form referred to as "Cold Rolled."
After heat treatment, the material achieves a hardness range of 370-580 HV. Primary application areas include the automotive sector and saw production. Commonly used quality grades include: C45 (CK45), C67 (CK67), C75 (CK75).
