The quality state of materials, i.e., products is realized in the procedure of the cold processing and applying an appropriate correlation between the degree of the cold processing and the conditions of the interphase finish tempering.

The most part of material quality is determined by the international standards. The standard (commercial) material qualities have a wide field of application, while the special material states are used in the precisely defined fields of application.

The quality state of a material is determined by the customer alone or by being adviced by the producer.
