Abstract
1. At room temperature the deformation rate has no effect on the physicomechanical properties of steels 12Kh18N10T and 15Kh18N12S4TYu. 2. In comparison with static deformation, dynamic deformation at −196° leads to greater overall elongation and percentage of even elongation, permitting larger deformations. This provides the same ultimate tensile strength as static deformation without impairing the ductility. 3. The strength characteristics of the steels after dynamic deformation at −196° are considerably higher than after the standard treatment (static deformation at room temperature).
