Abstract

DONDE DICHO ACERO CONTIENE MENOS DE 9% POR PESO DE NIQUEL, Y TIENEN UNA RESISTENCIA A LA TRACCION APROXIMADA DE 830 MPa CUANDO ES SOLDADO Y UNA MICROESTRUCTURA QUE COMPRENDE MARTENSITA EXPANDIDA DE GRANO FINO TEMPLADA, BAINITA INFERIOR DE GRANO FINO TEMPLADA, BAINITA GRANULAR FINA TEMPLADA (BGF) O MEZCLA DE ESTAS. DONDE DICHO ACERO SE PREPARA : a) CALENTANDO UNA CHAPA GRUESA DE ACERO QUE CONTIENE Fe Y PORCENTAJES POR PESO ESPECIFICADOS DE ALGUNO O TODOS LOS ADITIVOS DE C, Mn, Ni, N, Cu, Cr, Mb, Nb, V, Ti, Al Y B; b) REDUCIENDO LA CHAPA PARA FORMAR UNA PLACA EN UNA O MAS PASADAS EN UN LIMITE DE TEMPERATURA A LA CUAL SE CRISTALIZA LA AUSTENITA; c) TERMINANDO EL LAMINADO DE LA PLACA EN UNA O MAS PASADAS DENTRO DE UN LIMITE DE TEMPERATURA POR DEBAJO DE LA TEMPERATURA DE CRISTALIZACION DE LA AUSTENITA Y SOBRE LA TEMPERATURA A LA CUAL COMIENZA LA AUSTENITA A TRANSFORMAR LA FERRITA DURANTE EL ENFRIAMIENTO; d) TEMPLANDO LA PLACA LAMINADA TERMINADA A UNA TEMPERATURA DE DETENCION DEL TEMPLADO; e) DETENIENDO EL TEMPLADO; Y f) TEMPLANDO LA PLACA A UNA TEMPERATURA APROPIADA DURANTE UN PERIODO DE TIEMPO SUFICIENTE PARA OCASIONAR LA PRECIPITACION DE LAS PARTICULAS ENDURECEDORASWHERE SUCH STEEL CONTAINS LESS THAN 9% BY WEIGHT OF NICKEL, AND HAVE A STRENGTH TO THE TRACTION OF APPROXIMATE 830 MPa WHEN WELDED AND A MICROSTRUCTURE THAT INCLUDES EXPANDED MARTENSITE OF TEMPERED FINE GRAIN, BAINITA LOWER TEMPERED GRAIN OF FINE GRAIN (BGF) OR MIX OF THESE. WHERE SUCH STEEL IS PREPARED: a) HEATING A THICK SHEET OF STEEL CONTAINING Fe AND SPECIFIED PERCENTAGES BY WEIGHT OF SOME OR ALL OF THE ADDITIVES OF C, Mn, Ni, N, Cu, Cr, Mb, Nb, V, Ti, Al YB; b) REDUCING THE PLATE TO FORM A PLATE IN ONE OR MORE PASSES IN A TEMPERATURE LIMIT AT WHICH THE AUSTENITE IS CRYSTALIZED; c) FINISHING THE PLATE LAMINATION IN ONE OR MORE PASSES WITHIN A TEMPERATURE LIMIT BELOW THE CRYSTALIZATION TEMPERATURE OF THE AUSTENITE AND ABOVE THE TEMPERATURE AT WHICH THE AUSTENITE BEGINS TO TRANSFORM THE FERRITE DURING COOLING; d) TEMPERING THE FINISHED LAMINATE PLATE TO A TEMPERATURE STOPPING TEMPERATURE; e) STOPPING THE TEMPERATE; AND f) TEMPERING THE PLATE TO AN APPROPRIATE TEMPERATURE FOR A PERIOD OF TIME SUFFICIENT TO CAUSE THE PRECIPITATION OF THE HARDENING PARTICLES
