Abstract

"AçO E PROCESSO PARA PREPARAR UMA CHAPA DE AçO". São proporcionados um aço com alta resistência à tração possuindo uma excelente tenacidade ao longo da sua espessura, excelentes propriedades nas juntas soldadas, e uma resistência à tração (TS) de pelo menos aproximadamente 900 MPa, e um processo para produzir esse aço. Os aços de acordo com esta invenção possuem, e preferência, a seguinte composição baseada em % em peso: carbono (C): 0,02% a 0,1%; silício (Si): não mais que 0,60%; manganês (mn): 0,2% a2,5%: níquel (Ni): 0,2% a 1,2%; nióbio (Nb): 0,01% a 0,1% a 0,1%; titânio (Ti): 0,0005% a 0,03%; alumínio (Al): não mais que 0,1%; nitrogênio (N): 0,001% a 0,006%; cobre (Cu): 0% 0,6%; cromo (Cr): 0% a 0,8%; molibdênio (Mo): 0% a 0,6%; vanádio (V): 0% a 0,1%; boro (B): 0% a 0,0025%; e cálcio (Ca): 0% a 0,006%. O valor de Vs conforme definido por Vs=C+ (Mn/5)+5P-(Ni/10)-(Mo/15)+(Cu/10) é de 0,15 a 0,42. P e S entre as impurezas estão contidos em uma quantidade não maior que 0,015% e não maior que 0,003% respectivamente. O tamanho do carboneto no aço não é maior que 5 mícrons na sua direção longitudinal.
