A composition and method for the manufacture of products of a precipitation hardenable martensitic stainless steel, the composition of which comprises at least 0.5 % by weight of Cr and at least 0.5 % by weight of Mo wherein the sum of Cr, Ni and Fe exceeds 50 %. The method steps include smelting the material into a casting, hot extrusion followed by a number of cold deforming steps so as to obtain at least 50 % martensite and finally an ageing treatment at 425-525 °C to obtain precipitation of quasicrystalline particles. Such materiel can be used in vehicle components where demands for corrosion resistance, high strength and good toughness are to be satisfied.

L'invention concerne une composition et un procédé de fabrication de produits en acier inoxydable martensitique durcissable par précipitation, dont la composition contient au moins 0,5 % en poids de Cr et au moins 0,5 % en poids de Mo, la somme de Cr, Ni et Fe dépassant 50 %. Les étapes du procédé consistent en la fusion du matériau en une pièce coulée, l'extrusion à chaud suivie d'un certain nombre d'étapes de déformation à froid afin d'obtenir au moins 50 % de martensite et enfin un traitement de vieillissement à 425-525 DEG C pour obtenir une précipitation de particules quasi-cristallines. Ce matériau peut être utilisé dans des pièces de véhicules pour lesquelles il convient de satisfaire aux exigences de résistance à la corrosion, de haute résistance et de bonne ténacité.
