METHOD FOR PRODUCING STRUCTURAL ELEMENT MADE OF STEEL BY MEANS OF THERMOFORMING Russian patent published in 2017 - IPC C21D7/13 C21D8/02 B21D22/00 C23C2/26 

Abstract RU 2612478 C2

FIELD: machine building.

SUBSTANCE: method of manufacturing a structural element made of steel, amenable to transformation during hot forming comprises heating the cut steel sheet metal plate to the austenitizing temperature, moulding secured after moulding is at least partially martensitic structure, while in rapid cooling of the sheet or plate after heating to the austenitizing temperature, to obtain a plate with conditioned at least partly martensitic, and then reheating is carried out to a temperature below ac1-temperature conversion and forming at this temperature.

EFFECT: increase strength and corrosion resistance.
