Abstract

Process for the manufacture of components from untreated steel, comprising a succession of thermal treatment and forming operations, characterised by the following successive operations: - heating the steel to a temperature above the transformation (austenitisation) point, - isothermal quenching in a fluidised bed bath immediately following the austenitisation heating, endowing the steel with a bainitic structure, and - forming of the components at mild heat. t
