Abstract

La présente invention concerne un procédé d'emboutissage à chaud qui comprend les étapes suivantes consistant à : a. Prendre une feuille d'acier au carbone revêtue d'un prérevêtement barrière comprenant du nickel et du chrome, le rapport pondéral ni/cr étant compris entre 1,5 et 9, b. Découper la feuille d'acier au carbone revêtue pour obtenir un flan, c. Traiter thermiquement le flan dans une atmosphère ayant un pouvoir oxydant égal ou supérieur à celui d'une atmosphère constituée de 1 % en volume d'oxygène et égal ou inférieur à celui d'une atmosphère constituée de 50 % en volume d'oxygène, une telle atmosphère ayant un point de rosée compris entre -30 et +30 °c, d. Transférer le flan dans un outil de presse, e. Former à chaud le flan pour obtenir une pièce, f. Refroidir la pièce obtenue à l'étape e) afin d'obtenir une microstructure dans l'acier martensitique ou martensito-bainitique ou constituée d'au moins 75 % en poids de ferrite équiaxe, de 5 à 20 % en poids de martensite et de bainite dans une quantité inférieure ou égale à 10 % en poids.
