Abstract
Se describe un acero inoxidable martensítico cuya composición está restringida dentro de una zona específica para cada elemento. La capa de cascarilla formada sobre la superficie del material base consiste de una capa de cascarilla interna que comprende principalmente FeCr2O4 y una capa de cascarilla externa que tiene un espesor de no más de 20 micrones, estando la capa externa depositada sobre la capa de cascarilla interna con un grado de cubrimiento superficial no mas de 1% y no mas que 15%. La aplicación de aceite preservativo contra oxidación sobre la superficie del acero asegura una excelente resistencia a los agentes atmosféricos durante tiempos prolongados, pudiéndose proveer en consecuencia aceros inoxidables martensíticos que no forman oxido ya sea en depósitos al aire libre o en depósitos cerrados. El acero puede ser usado para fabricar no solamente tubos de acero, sino también chapas de acero, barras de acero y otros productos en un amplio campo de aplicación. El acero comprende en % en masa: C desde 0,15 a 0,22; Si desde 0,18 a 1,0; Mn desde 0,05 a 1,0; Cr desde 10,5 a 14,0; Ni <0,20; Al <0,05; N <0,100; S: 0,015 y P: 0,020; siendo el resto Fe. En el proceso se calienta un material base que contiene dicho acero en un horno de templado a una temperatura comprendida entre 850 y 980°C, se decapa totalmente la capa de cascarillas formadas, se enfría bruscamente el material base, se realiza un revenido y se decapa parcialmente la capa de cascarilla nuevamente formada sobre la superficie de dicho material para formar una cascarilla terminada.
