Title (EN) STEEL FOR SHIP BALLAST TANK AND SHIP
(FR) MATÉRIAU D’ACIER POUR RÉSERVOIR DE BALLAST DE NAVIRE, ET NAVIRE
(JA) 船舶バラストタンク用鋼材および船舶
Abstract: front page image
(EN)Provided is steel for a ship ballast tank for which both excellent corrosion resistance and excellent lamellar tear resistance have been established as a result of the steel having a specified component composition and the ACB value thereof being 0.50 or less and Sn segregation being less than 18.
(FR)L’invention fournit un matériau d’acier pour réservoir de ballast de navire qui tout en présentant une composition prédéfinie, concilie d’excellentes propriétés de résistance à la corrosion et à l’arrachement lamellaire, en raison d’une valeur ACB inférieure ou égale à 0,50 et d’un degré de ségrégation de Sn inférieur à 18.
(JA)所定の成分組成にするとともに、ACB値を0.50以下、Sn偏析度を18未満とすることにより、優れた耐食性と優れた耐ラメラテア性とを両立した船舶バラストタンク用鋼材を提供する。
