Abstract

Corrosion tests are performed on developed chromium corrosion-resistant steels alloyed with nitrogen. A set of tests shows that depending on chemical composition and production parameters the corrosion resistance indices for steels of one class may differ by an order of magnitude. Revelation of a dependence makes it possible to conclude that an increase within steel of nitrogen and molybdenum content combined with quenching and low-temperature tempering at 400°C makes it possible to prepare steel with good pitting corrosion resistance in aqueous media, particularly, under sea water conditions.
