Abstract

EL INVENTO SE REFIERE A AL APLICACION DE ACEROS EN FORMA DE BANDAS LAMINADAS EN FRIO O EN CALIENTE Y CON BUENAS PROPIEDADES DE TRANSFORMACION Y DE SOLDADURA COMO MATERIA ACTIVA PARA LA PRODUCCION DE COMPONENTES RESISTENTES A LA CORROSION QUE SE EMPLEAN A UNA TEMPERATURA DE CASI 950 C. EL ACERO ESTA FORMADO POR UN 0,02% EN PESO DE C, UN 1,0% DE SI, UN 1,0% DE MN, 0,045% DE P, 0,030% DE S, 14,5 A 16,0% EN PESO DE CR, 0,0% EN PESO DE NI, 0,5% DE MO, 0,020% DE N, DE 0,4 A 1,0% EN PESO DE NB, DE 0,2 A 1,0% EN PESO DE TI, DE 0,10 A 0,50% EN PESO DE ZR, EL RESTO HIERRO E IMPUREZAS USUALES. LA RELACION ENTRE NB/TI/ZR ESTA COMPRENDIDO ENTRE 2,0 A 3,5/ 2,0 A 3,5/ 1,0 A 1,5 Y LA SUMA DE NB, TI Y ZR SUPONE UN 1,8%.THE INVENTION REFERS TO THE APPLICATION OF STEELS IN THE FORM OF COLD OR HOT ROLLED BELTS AND WITH GOOD PROPERTIES OF TRANSFORMATION AND WELDING AS AN ACTIVE SUBSTANCE FOR THE PRODUCTION OF CORROSION RESISTANT COMPONENTS USED AT A TEMPERATURE OF ALMOST 950 C STEEL IS FORMED BY 0.02% BY WEIGHT OF C, 1.0% BY SI, 1.0% BY MN, 0.045% BY P, 0.030% BY S, 14.5 TO 16.0% IN CR WEIGHT, 0.0% IN NI WEIGHT, 0.5% OF MO, 0.020% OF N, FROM 0.4 TO 1.0% IN WEIGHT OF NB, FROM 0.2 TO 1.0% IN IT WEIGHT, FROM 0.10 TO 0.50% BY ZR WEIGHT, THE REST IRON AND USUAL IMPURITIES. THE RATIO BETWEEN NB / TI / ZR IS INCLUDED BETWEEN 2.0 TO 3.5 / 2.0 TO 3.5 / 1.0 TO 1.5 AND THE SUM OF NB, TI AND ZR IS 1.8%.
