Abstract

L'invention concerne un acier coulé de manganèse à faible alliage structural ayant une dureté et une résistance à l'usure accrues, et un article fabriqué à partir de celui-ci. En particulier, après la réalisation d'un durcissement massif classique suivi d'une trempe, l'acier selon l'invention a une dureté d'environ 418 à 512 HB et est approprié pour une utilisation en ingénierie ferroviaire, en particulier pour la fabrication de pièces de bogies de train de marchandises telles qu'un coin de frottement. En raison de la dureté et de la résistance à l'usure améliorées des pièces fabriquées en acier selon la présente invention, une augmentation de la durée de vie utile entre des réparations, en particulier, de la paire de frottement constituée du coin de frottement et de la plaque de frottement, est fournie sans augmentation significative du coût des pièces.
