Abstract

Se proporciona en la presente un tubo de acero sin costura de alta resistencia y baja aleación para productos tubulares de región petrolífera que tiene alta resistencia con un límite elástico de 862 MPa o más, y excelente resistencia al agrietamiento por corrosión bajo tensión en presencia de sulfuros (resistencia a SSC) en un entorno saturado con gas sulfuro de hidrógeno a alta presión. El tubo de acero de la presente invención tiene una composición que contiene, en % en masa, C: 0.25 a 0.50%, Si: 0.01 a 0.40%, Mn: 0.45 a 0.90%, P: 0.010% o menos, S: 0.001% o menos, O: 0.0015% o menos, Al: 0.015 a 0.080%, Cu: 0.02 a 0.09%, Cr: 0.9 a 1.5%, Mo: 1.4 a 2.0%, Nb: 0.005 a 0.05%, B: 0.0005 a 0.0040%, Ca: 0.0010 a 0.0020%, Mg: 0.001% o menos, y N: 0.005% o menos, y en la cual el resto es Fe e impurezas incidentales. El tubo de acero tiene una microestructura en la cual el número de inclusiones no metálicas de base óxido que incluyen CaO, Al2O3, y MgO y que tienen un diámetro exterior de 5 µm o más en el acero, y que satisfacen las relaciones de composición representadas por las siguientes fórmulas (1) y (2) es de 5 o menos por 100 mm2, y en la cual el número de inclusiones no metálicas de base óxido que incluyen CaO, Al2O3, y MgO y que tienen un diámetro exterior de 5 µm o más en el acero, y que satisfacen las relaciones de composición representadas por las siguientes fórmulas (3) y (4) es de 20 o menos por 100 mm2. (CaO)/(Al2O3) = 0.25 (1) 1.0 = (Al2O3)/(MgO) = 9.0 (2) (CaO)/(Al2O3) = 2.33 (3) (CaO)/(MgO) = 1.0 (4) En las fórmulas, (CaO), (Al2O3), y (MgO) representan los contenidos de CaO, Al2O3, y MgO, respectivamente, en las inclusiones no metálicas de base óxido en el acero, en % en masa.
