Abstract
The article provides the substantiation of the specific coefficient of corrosion influence, considered per unit of the limit of short-term strength of the metal, with the help of which it is possible to simplify the most approximate calculation of the limited endurance limit of steels of oil and gas equipment operating under cyclic loads, as well as perform subsequent resource calculations.
