A process for producing a metal member having improved fatigue life via a simple process. The process for producing a metal member comprises a burr removal step of removing burrs from the corners and edges of a metal member, and a projection step, which is performed after the burr removal step, without performing a chamfering treatment, of projecting particles having an average particle size of not less than 10 µm and not more than 400 µm onto a surface of the metal member.

L'invention porte sur un procédé pour fabriquer un élément métallique dont l'endurance est améliorée grâce à un traitement simple. Le procédé de fabrication d'élément métallique comprend un traitement d'ébavurage pour éliminer les bavures sur les angles et arêtes de l'élément métallique et un procédé de projection de particules dans lequel des particules ayant une dimension de particule moyenne de 10-400 µm sont projetées sur la surface dudit élément métallique de telle sorte qu'il n'est pas nécessaire d'effectuer un biseautage après le traitement d'ébavurage.
