Abstract
The resistance of high-strength corrosion-resistant nitrogen Cr – Ni – Mn steels to microbiological corrosion is investigated. It is shown that lowering of the nickel content and elevation of the content of manganese lowers the corrosion strength of the steels in a synthesized solution of sulfate-reducing bacteria, whereas the additions of copper and nitrogen raise this strength. Surface defects and roughness intensify localization of the corrosion damage and accelerate the corrosion process in the steels.
