To die steels include tool steels with special properties designed for the manufacture of tooling, moulds, forms, metal casting parts and dies.

Group Features
Die steel for cold deformation of metal Steel designed for the manufacture of dies, stamping cold metal. After final heat treatment has a high hardness on the cutting edges and working surfaces, high wear resistance, necessary to maintain the size and shape of the working edges in the stamped, high strength working edges that act directly on the processed material and parts of the stamp, which perceive the highest torsional and bending loads
Die steel for hot deformation of metals Die steel must maintain the required properties at very high temperatures. With heat treatment these steels achieve moderate hardness in combination with high viscosity in comparison with the other groups of steels
Die steels, corrosion-resistant Die steel, designed for forms of casting metals under pressure and matrix molds. This die mark resistant to aggressive environments, reactive plastics, thermal action of the cast metal,

Demands on die steels

In cold and hot workability needs to succumb to the pressure treatment and machining;

The hardness, combined with high viscosity;

Good hardenability: should have a uniform high hardness, homogeneous crystalline structure in depth;

Slight by heat treatment deformation;

Low sensitivity to overheating: needs to toughen up in a rather large temperature range;

A good polishing and sanding behaviour — defines the standard surface quality of the product during stamping;

Minor sensitivity to decarburization in the process of filament winding the hardness of the surface of the working layer.
