Abstract

resumo ?fio-máquina laminado a quente? a presente invenção fornece um fio-máquina laminado a quente tendo alta resistência e excelente resistência à ssc. é revelado um fio-máquina laminado a quente incluindo, em porcentagem em massa: c: 0,20 a 0,5%, si: 0,05 a 0,3%, mn: 0,3 a 1,5%, al: 0,001 a 0,1%, p: excedendo 0% e 0,01% ou menos, e s: excedendo 0% e 0,01% ou menos, com o equilíbrio sendo ferro e impurezas inevitáveis. quando o teor de enxofre no fio-máquina laminado a quente é medido em 300 locais ou mais em intervalos de 200 µm usando um microanalisador de feixe de elétrons, uma razão de segregação (smax/save) é 30 ou menos, em que uma razão de segregação é definida como uma razão do teor máximo de enxofre smax (% em massa) para um teor médio de enxofre save (% em massa).overview? hot rolled wire rod? The present invention provides a hot rolled wire rod having high strength and excellent resistance to ssc. a hot-rolled wire rod is disclosed including by mass percentage: c: 0.20 to 0.5%, si: 0.05 to 0.3%, mn: 0.3 to 1.5%, al : 0.001 to 0.1%, p: Exceeding 0% and 0.01% or less, s: Exceeding 0% and 0.01% or less, with balance being iron and unavoidable impurities. When the sulfur content of the hot-rolled wire rod is measured at 300 locations or more at 200 µm intervals using an electron beam microanalyzer, a segregation ratio (smax / save) is 30 or less, where a ratio segregation is defined as a ratio of the maximum sulfur content smax (mass%) to an average sulfur content save (mass%).
