Abstract : Specimens of 30KhGSA steel were subjected to tensile test after standard heat treatment, and also after large plastic deformation followed by stress relieving at 200, 300, 350, or 625C for 2-30 min. The tensile and yield strength of unstrained specimens (118 and 85 kg/sq mm, respectively) slightly decreased with annealing at 360C for 20 min. The strength of plastically prestrained specimens was not affected by annealing at 200C for 2-10 min. Annealing at 300-370C for 10-30 min slightly increased the strength of the steel. The strengthening effect of annealing depended on the magnitude of relative plastic deformation and averaged 5-10%. However, annealing at 625C for 20 min significantly decreased the yield strength of prestrained specimens. The elastic limit of 30KhGSA steel was 41 kg/sq mm.
