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 kgsq 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 kgsq mm.
