Abstract
The proposed corrosion-resistant steel contains carbon, silicon, manganese, chromium and iron and in addition contains a plasticity-enhancing nitration-boosting chemical element and vanadium. The relative proportions in wt.% are as follows: carbon 0.10-0.63; silicon 0.20-1.20; manganese 0.40-0.60; chromium 13.4-16.5; plasticity-enhancing and nitration-boosting chemical element 0.40-1.20; vanadium 0.15-0.35; iron - the rest. The plasticity-enhancing and nitration-boosting chemical element is copper or germanium.

In the course of research, they use the polarized fast, but they quickly calculate the speed of steel. Also, specific laboratory studies are produced, as a result of which they quickly establish the influence of mechanical loads, pressure, temperature, speed. These studies are aimed at identifying cross-border cruelty, obstruction, voltage, physical impairment, and physical impairment. The main indicator of the speed of the destruction of the territory, as well as the local, the same and the depth of the river, is the depth of the river. In general, the depth of destruction is measured in millimeters per year. In case of equilibrium with the use of deep-seated equipment (,P, mm / year), it calculates the value
