Abstract

Tubo de acero sin costura con alta resistencia y excelente tenacidad a baja-temperatura y que tiene propiedades de resistencia a la fragilización por hidrógeno. El tubo de acero sin costura tiene una composición química descrita en las especificaciones, y la composición química satisface [5C + Mo + Cr ³ 1.00], y satisface [GN - 1.96 × (Mn + 70P + 100N) ³ 7.50] y [GN - 1.37 × (Mn + 85P - 30Ca) ³ 8.90] en conjunto con un número de tamaño de grano de g-previa GN. El tubo de acero sin costura tiene una resistencia a la tracción de 1200 MPa o más, y una concentración crítica de hidrógeno de 2.5 ppm o más.Seamless steel tube with high strength and excellent low-temperature toughness and having hydrogen embrittlement resistance properties. The seamless steel pipe has a chemical composition described in the specifications, and the chemical composition satisfies [5C + Mo + Cr ³ 1.00], and satisfies [GN - 1.96 × (Mn + 70P + 100N) ³ 7.50] and [GN - 1.37 × (Mn + 85P - 30Ca) ³ 8.90] in conjunction with a grain size number of g-previa GN. Seamless steel pipe has a tensile strength of 1200 MPa or more, and a critical hydrogen concentration of 2.5 ppm or more.
