The structure, mechanical properties and corrosion resistance of steel 08KhFA are studied after tempering at different temperatures. The succession of the structural changes and the temperature ranges of the phase and structural transformations occurring in tempering of lath, carbide-free and low-carbon bainite are determined. The structural features of lath bainite in steel 08KhFA, the process modes providing its formation, and the combination of high strength properties with corrosion resistance under oilfield operating conditions are presented.
