摘要： A thick steel plate for tanks which contains given components and satisfies the relationship (Ti content [Ti])×(N content [N])‰¥0.000085 and in which the nonmetallic particles having a size of 1 µm or larger in terms of equivalent circular diameter have a specific average composition and the Ti-containing nitrides satisfy specific average number densities.
