Abstract
trata-se de uma placa de aço de acordo com uma modalidade que tem uma composição química especificada. o indicador q determinado a partir da fórmula (1) é 0,00 ou mais. a quantidade equivalente de carbono equivalente de carbono ceq (%)determinada a partir da fórmula (2) é menos que 0,800%. a razão da diferença entre a dureza de superfície e a dureza no centro na direção de espessura de placa em relação à dureza de superfície em temperatura ambiente é 15,0% ou menos. a dureza de superfície em temperatura ambiente é uma dureza vickers de 400 ou mais, e a espessura de placa é de 40 mm ou mais. fórmula (1): q = 0,18 -1,3(logt) + 0,75(2,7 × [c] + [mn] + 0,45 × [ni] + 0,8 × [cr] + 2 × [mo]) fórmula (2): ceq (%) = [c] + [mn]/6 + [si]/24 + [ni]/40 + [cr]/5 + [mo]/4 + [v]/4It is a steel plate according to one embodiment having a specified chemical composition. The indicator q determined from formula (1) is 0.00 or more. the carbon equivalent amount of carbon equivalent cq (%) determined from formula (2) is less than 0,800%. The ratio of the difference between surface hardness and center hardness in the direction of plate thickness relative to surface hardness at room temperature is 15.0% or less. The surface hardness at room temperature is a vickers hardness of 400 or more, and the plate thickness is 40 mm or more. formula (1): q = 0.18 -1.3 (logt) + 0.75 (2.7 × [c] + [mn] + 0.45 × [ni] + 0.8 × [cr] + 2 × [mo]) formula (2): ceq (%) = [c] + [mn] / 6 + [si] / 24 + [ni] / 40 + [cr] / 5 + [mo] / 4 + [v] / 4
