Abstract

METODO DE PRODUCCION DE UN ACERO INOXIDABLE AUSTENITICO SOLDABLE EN SECCIONES GRUESAS. COMPRENDE LA FUSION, COLADO, LAMINADO EN CALIENTE Y LAMINADO EN FRIO DEL ACERO A UN CALIBRE FINAL MAYOR A 0,065 PULGADAS (1,65 MM), RECOCIENDO TOTALMENTE EL ACERO DE CALIBRE FINAL A TEMPERATURAS SUPERIORES A 1.900JF (1.038JC) Y MENORES DE 2.100JF (1.149JC) PARA PRODUCIR UN ACERO SUSTANCIALMENTE LIBRE DE LA PRECIPITACION DE SEGUNDA FASE, DANDO COMO RESULTADO LA SUPRESION DE LA FASE SIGMA, RETARDANDO EL ATAQUE DE LA PRECIPITACION E INCREMENTANDO LA TEMPERATURA CRITICA DE LA CORROSION EN GRIETAS, PUDIENDO INCLUIR LA SOLDADURA DEL ACERO DE SECCION GRUESA PARA PRODUCIR ARTICULOS SOLDADOS QUE ESTAN SUSTANCIALMENTE LIBRES DE LA PRECIPITACION DE SEGUNDA FASE, INCLUYENDO LA SOLDADURA EL USO DE UN METAL RELLENADOR DE SOLDADURA QUE LLEVA NITROGENO. EL ACERO OBTENIDO COMPRENDE, EN PESO, DE 20 A 40% DE NIQUEL, 14 A 21% DE CROMO, 6 A 12% DE MOLIBDENO, 0,15 A 0,30% DE NITROGENO, Y EL RESTO HIERRO.
