Abstract

The influence of alloying on the properties of high-tempered steels used for the production of casing pipes has been studied. It has been shown that an increase of molybdenum content from 0.15 to 0.53% provides a noticeable increase of the mechanical characteristics in chromium-molybdenum steels after tempering at 600‒690 °C. Alloying with vanadium and niobium contributes to an additional increase in strength properties. The influence of vanadium on the highly viscoplastic properties of steels is shown. It has been established that the greatest strengthening of steel with 0.32% molybdenum in a highly tempered state is provided by complex alloying with niobium and vanadium. The influence of austenitization and tempering temperature on the structure and properties, including resistance to cracking in an environment saturated with hydrogen sulfide, of chromium-molybdenum steel grade 26CrMoVNb-2 with micro-alloying additives of vanadium and niobium was determined. Alloying with molybdenum, vanadium and niobium makes it possible to obtain steels for high-strength casing pipes that are resistant to brittle fracture and sulfide stress corrosion cracking, subject to comprehensive consideration of the main factors such as austenitization temperature, tempering temperature and duration, dispersion and homogeneity of microstructure
