Influence of Metallurgical Quality on Anisotropy of Plastic Properties of Constructional Steels

Abstract

Influence of metallurgical quality on anisotropy of plastic properties of constructional steels is considered. It is shown, that at increase in the maintenance of sulfur in a steel considerably raise striation and anisotropy of such parameter of mechanical properties, as impact strength. It is received, that for extra high tensile steels at the limiting maintenance of sulfur of value of impact strength at a longitudinal and cross-section direction of fibers differ 6–8 times.
