Hydrogen sulfide corrosion cracking of steel occurs in deposits containing corrosive components - hydrogen sulfide and carbon dioxide (carbon dioxide). The mechanism of corrosion cracking of steel in hydrogen sulfide-containing environments of corrosive oil and gas fields is considered, and factors influencing hydrogen sulfide cracking are identified. Increasing the performance properties of carbon, low-alloy, structural steels resistant to hydrogen sulfide and sulfide cracking was carried out on the basis of improving the composition of the components of chemical elements and the structural state through the choice of heat treatment methods depending on the acidity and temperature of the environment, partial pressures of carbon dioxide and hydrogen sulfide. Laboratory and production tests have shown the durability of the proposed compositions chemical elements of steels to hydrogen sulfide cracking, sulfide cracking and hydrogen swelling in deposits containing corrosive components was 70–80% compared to existing carbon structural steels.
