Abstract

Se describe una aleación de acero inoxidable martensítica de grano fino a base de hierro. La aleación está esencialmente libre de ferrita delta y proporciona una dureza muy alta y buena resistencia a la corrosión. La aleación consiste esencialmente en la siguiente composición en por ciento en peso. C de aproximadamente 0.20 a aproximadamente 0.70 Mn aproximadamente 5 máx. Si aproximadamente 1 máx. P aproximadamente 0.1 máx. S aproximadamente 0.03 máx. Cr de aproximadamente 7.5 a aproximadamente 15 Ni de aproximadamente 2 a aproximadamente 5 Mo aproximadamente 4 máx. Co aproximadamente 4 máx. Cu aproximadamente 1.2 máx. Ti de aproximadamente 0.01 a aproximadamente 0.75 Al aproximadamente 0.2 max Nb aproximadamente 1 máx. V aproximadamente 2 máx. N aproximadamente 0.02 máx. B aproximadamente 0.1 máx. Lo que resta de la aleación es de hierro y las impurezas habituales. También se describe un artículo compuesto de fabricación que incluye una parte de cubierta formada de la aleación anterior.
