The variant of a quantitative estimation of treatability metals by pressure on standard test methods of mechanical properties is offered. Communications of scientific and engineering characteristics of an estimation of deformability for use of results of scientific researches in factory practice are received, being guided on standard test methods. The example of use of the received equations for an estimation of limiting elongation ratio for a number of steels in processes of rolling and drawings is resulted. The offered technique can be used for an estimation treatability new steels and alloys
