Stamping steels are tool steels with special properties, designed for the manufacture of technological equipment, molds, metal casting forms, stamp parts.

Groups Characteristics
Cold forming die steels Steels are designed for the manufacture of dies and cold metal stamping. After the final heat treatment: has high hardness on cutting edges and working surfaces, high wear resistance necessary to maintain the dimensions and shape of the working edges when the die is in operation, high strength of the working edge acting directly on the material to be worked and the die areas that take the greatest torsional and bending loads
Steel for hot workpiece forming Hot stamping steels must retain their required properties at very high temperatures. These steels are heat treated to achieve a moderate hardness combined with a high toughness as compared to other steel groups
Corrosion-resistant stamping steels A stamping steel designed for metal injection molds and die castings. This stamping steel grade is resistant to aggressive media, chemically active plastics and the thermal action of the metal being cast,

Requirements for stamping steel

In cold and hot condition, the manufacturability must be amenable to pressure and cutting treatment;

Hardness combined with high toughness;

Good hardenability: must have homogeneous high hardness, homogeneous fine crystalline structure in depth;

Insignificant deformation during heat treatment;

Low sensitivity to overheating: must harden in a fairly large temperature range;

Good polishability and grindability - determines the standard of surface quality of products when stamping;

Negligible sensitivity to decarburization during heat treatment, which reduces the hardness of the surface working layer.
