Heat treatment of BSt500S steel rebar

This paper deals with the analysis of mechanical properties of BSt500S steel rebar. First, the bars were quenched and self-tempered. Yield strength and ultimate tensile strength values have been investigated, as well as the distribution of hardness upon the bars cross-section. The chemical composition and microstructure of the processed samples have been controlled, too. The results of the mechanical properties and micro-structural tests were compared with the mechanical properties of ordinary steel (Č.0551 – HR norm) rebar without heat treatment. The possible improvements (especially for continuous achieving of standard mechanical values) have been suggested in the conclusion.
