Abstract

UN METODO DE TRATAMIENTO TERMICO DE UN CUERPO DE ACERO RESISTENTE A LA CORROSION QUE ESTA PREFERIBLEMENTE, EN FORMA DE BOBINA, TENIENDO UNA TEMPERATURA DE TRANSFORMACION ANSTENITICA A FERRITA Y CARBURO ENTRE 650 Y 850 (GRADOS) C Y UNA COMPOSICION QUE DA LUGAR A UN ACERO CON PROPIEDADES MECANICAS TIPICAS COMO SIGUE. TENSION DE PRUEBA 350 MPA, DE TRACCION ULTIMA 520 MPA, ALARGAMIENTO DE 25% Y DUREZA BRINELL 164 Y EN EL QUE ESTAN AUSENTES LAS MICROESTRUCTURAS MATENSITICAS GENERALMENTE; A VELOCIDADES DE ENFRIAMIENTO INFERIORES A 5 (GRADOS) C/MIN, Y EL METODO COMPRENDE: TRABAJO EN CALIENTE DEL CUERPO DE ACERO, POR ENCIMA DE LA TEMPERATURA DE TRANSFORMACION; ENFRIAMIENTO DEL ACERO TRABAJANDO EN CALIENTE POR DEBAJO DE LA TEMPERATURA DE TRANSFORMACION A UNA VELOCIDAD DE ENFRIAMIENTO ENTRE 10 Y 1 (GRADOS) C/MIN DETERMINADA PARA ASEGURAR GENERALMENTE LA AUSENCIA DE MICROESTRUCTURAS DE CUARTENSITA A TRAVES DEL CUERPO.
