Abstract

LA PRESENTE INVENCION SE REFIERE A UNA ALEACION DE ACERO MARTENSITICO QUE PUEDE ENDURECERSE MEDIANTE ENVEJECIMIENTO QUE PRESENTA LA COMBINACION UNICA DE UNA RESISTENCIA MUY GRANDE Y DE UNA BUENA TENACIDAD; ESTA ALEACION ESTA COMPUESTA BASICAMENTE, EN PORCENTAJE DE PESO, POR ALREDEDOR DE: C: 0,21-0,34; MN: 0,20 MAXIMO; SI: 0,10 MAXIMO; P: 0,008 MAXIMO; S: 0,003 MAXIMO; CR: 1,5-2,80; NO: 0,90-1,80; NI: 10-13; CO: 14,0-22,0; AL: 0,1 MAXIMO; TI: 0,05 MAXIMO; CE: 0,030 MAXIMO; LA: 0,010 MAXIMO; ESTANDO COMPUESTO EL RESTO BASICAMENTE DE HIERRO. ADEMAS, SE EQUILIBRA EL CERIO Y EL AZUFRE DE FORMA QUE LA RELACION CE/S SEA COMO MINIMO DE ALREDEDOR DE 2 Y NO SOBREPASE APROXIMADAMENTE 15. SE PUEDE UTILIZAR UNA CANTIDAD PEQUEÑA, PERO SUSTANCIAL, DE CALCIO EN LUGAR DE LA TOTALIDAD O DE PARTE DEL CERIO Y DEL LANTANO.
