Abstract
DONDE LA PIEZA DE ACERO TIENE UNA COMPOSICION QUIMICA QUE COMPRENDE, EN PESO: 0,10%<C<0,22%; 0,5%<Si<1,5%; Al<0,9%; 0%<Mn<3%; 0%<Ni<5%; 0%<Cr<4%; 0%<Cu<1%; 0%<Mo+W/2<1,5%; 0,0005%<B<0,01%; N<0,025%; EVENTUALMENTE AL MENOS UN ELEMENTO ESCOGIDO ENTRE V, Nb, Ta, S y Ca EN CANTIDADES INFERIORES A 0,3%, Y/O ENTRE Ti y Zr EN CANTIDADES INFERIORES O IGUALES A 0,5%; SIENDO EL RESTO Fe E IMPUREZAS RESULTANTES DE LA ELABORACION. LOS CONTENIDOS DE Al, B, Ti y N CUMPLEN LA SIGUIENTE RELACION: B>K/3+0,5 SIENDO K = Min(I'; J'); I' = Max(0; I); J' = Max(0; J); I = Min(N; N-0,29*(Ti-5)); J = Min(N; 0,5*(N-0,52*Al+((N-0,52*Al)2+283)1/2). LOS CONTENIDOS EN Si y Al CUMPLEN LA SIGUIENTE CONDICION: si C>0,145 ENTONCES Si+Al<0,95. LA ESTRUCTURA DEL ACERO ES BAINITICA, MARTENSITICA O MARTENSITO-BAINITICA Y COMPRENDE ADEMAS DE 3% A 20% DE AUSTENITA RESIDUAL. LA COMPOSICION QUIMICA CUMPLE LA SIGUIENTE RELACION: 1,1%Mn+0,7%Ni+0,6%Cr+1,5(%Mo+%W/2)>1. EL PROCEDIMIENTO INCLUYE: a) AUSTENITIZAR LA PIEZA POR CALENTAMIENTO A UNA TEMPERATURA COMPRENDIDA ENTRE AC2 Y 1000°C; b) ENFRIAR HASTA UNA TEMPERATURA INFERIOR O IGUAL A 200°C DE MODO QUE EN EL NUCLEO DE LA PIEZA LA VELOCIDAD DE ENFRIAMIENTO ENTRE 800°C Y 500°C SEA SUPERIOR O IGUAL A LA VELOCIDAD CRITICA BAINITICA; Y, c) EVENTUALMENTE EFECTUAR UN REVENIDO A UNA TEMPERATURA INFERIOR O IGUAL A AC1 DURANTE UN TIEMPO INFERIOR A 10 h CON UN ENFRIAMIENTO HASTA UNA TEMPERATURA INFERIOR O IGUAL A 200°C
