Abstract
Properties of low-alloy boron-containing steels Brinar 400 and Brinar 500 in as-delivered and normalized conditions areconsidered. Charpy tests carried out within temperature ranges of ductile-to-brittle transition were followed by fractographicanalysis. The tests were carried out on specimens with their axes parallel and perpendicular to hot-working direction, at−40∘C,−20∘C, 0∘C, and +20∘C. The determined impact properties of Brinar steels were complemented with fractographic analysisperformed with use of a scanning electron microscope. It was found that temperatures of ductile-brittle transition were significantlydifferent for the materials in as-delivered and normalized conditions. In addition the tensile tests were carried out, determiningbasic strength properties of the analyzed materials.
