METHOD OF PRODUCING STRUCTURAL ELEMENT BY MEANS OF HOT PRESSURE TREATMENT OF SEMI-FINISHED PRODUCT FROM STEEL Russian patent published in 2016 - IPC C21D7/02 C21D9/08 C21D9/48

Abstract RU 2581948 C2

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, specifically to production of a structural element by means of hot pressure treatment of semi-finished product made of steel. Method of producing structural element by means of hot pressure treatment of semi-finished product made of steel includes cold pressure treatment with deformation degree of at least 3 %, heating of semi-finished product to temperature below temperature Ac₁ of phase transition and plastic deformation.

EFFECT: higher strength of structural element.
