METHOD OF PRODUCING STRUCTURAL ELEMENT BY MEANS OF HOT PRESSURE TREATMENT OF SEMI-FINISHED PRODUCT FROM STEEL

摘要

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 Acof phase transition and plastic deformation.EFFECT: higher strength of structural element.13 cl
