Influence of Deformation Heredity on the Physicomechanical Properties of 08Kh18N10T Steel

The influence of thermomechanical heredity on the physicomechanical properties of 08Kh18N10T steel, which is used in the manufacture of the furnace coils for diesel fuel hydrotreating units, is studied. Preliminarily deformed samples are shown to change their strength, plasticity, and creep characteristics. The features that determine the behavior of steel under thermomechanical treatment are revealed. The application of various loading cycles combined with thermal treatment is found to significantly increase the mechanical characteristics. Thermomechanical heredity also significantly affects the microstructure of the steel, which determines its performance characteristics and guarantees the reliability and safety of oil refining units.
