Abstract

AbstractIn this paper, we present the results of laboratory studies of the effect of the tempering temperature of hardened rolled structural steel with a carbon content of 0.18–0.20% on changes in the structure, the microstress level and dislocation density, mechanical properties and resistance to cracking in a hydrogen sulfide-containing environment. A metal structure with a microstress level of 0.08–0.075% and a dislocation density of 1.20 × 1013 m–2, a metal matrix hardness HV of less than 200, providing resistance against cracking in H2S environment, is shown to be formed after quenching at 920°C and tempering in the temperature range of 600–720°C.
