Abstract

The paper describes the methods of nondestructive control of the strength properties of steels under various loading conditions based on the results of measuring the plastic hardness. In particular, methods for determining the yield strength in tension, shear, crushing, bending, torsion are given. As an example of using the developed methods, an assessment of the equal strength of thread elements is given.
