Abstract
The article presents the results of a comprehensive study of high-strength Сr-Ni-Mo-V steels. The authors show the effect of heating temperature of quenching and tempering temperature on structuring and mechanical-property forming of high-strength low-alloy sheet steel. Impact strength and hardness of test samples and their alteration at different quenching-tempering temperatures have been determined. The results of the study can be applied in selecting optimal heat treatment conditions to obtain rolled products of high strength at conserving ductility and viscosity at an adequate level.
Keywords
