The results of experimental testing of production in the conditions of a casting and rolling complex (CRC) Vyksa Steel Works (VSW) of rolled products with a thickness of 8–10 mm with a reduced chromium content of strength class K52 to meet the requirements of the new guidelines of Rosneft on the corrosion resistance of metal in acidic environments. Based on the C–Mn–Si–Nb alloying system, a new chemical composition of steel with a reduced chromium content (0,40%) has been developed that provides a set of consumer properties — strength (tensile strength — 530–550 MPa, yield strength — 450–470 MPa), ductility (elongation — 28–34%), cold resistance (T50 below –80°C) and corrosion resistance against hydrogen cracking (CLR = 0%, CTR = 0%) and general corrosion in a CO2-containing medium (the rate of general corrosion is not more than 0,2 mm/year). It is shown that the variation of the chromium content in the range of 0,4–0,7% does not significantly affect the rate of general corrosion both under the influence of 5% sodium chloride solution and 5% sodium chloride solution with the addition of 0,40% sodium acetic acid solution when kept in an aggressive environment for 96 hours.
