Title (EN) STEEL, PRODUCT CREATED FROM SAID STEEL, AND MANUFACTURING METHOD THEREOF
(FR) ACIER, PRODUIT RÉALISÉ EN CET ACIER, ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) The invention relates to steel, the composition of which is, in wt%: 10.0% ≤ Ni ≤ 24.5%, 1.0% ≤ Mo ≤ 12.0%, 1.0% ≤ Co ≤ 18.0%, 14.0% ≤ Mo + Co + Si + Mn + Cu + W + V + Nb + Zr + Y + Ta + Cr + C + Al + B + Ti + N ≤ 29.0%, 21.5% ≤ Ni + Co + Mo ≤ 40.0%, traces ≤ Al ≤ 4.0%, traces ≤ Ti ≤ 0.1%, traces ≤ N ≤ 0.010%, traces ≤ Si ≤ 4.0%, traces ≤ Mn ≤ 13.0%, traces ≤ C ≤ 0.03%, traces ≤ S ≤ 0.0020%, traces ≤ P ≤ 0.005%, traces ≤ B ≤ 0.01%, traces ≤ H ≤ 0.0005%, traces ≤ O ≤ 0.03%, traces ≤ Cr ≤ 5.0%, traces ≤ Cu ≤ 4.0%, traces ≤ W ≤ 6.0%, traces ≤ Zr ≤ 4.0%, traces ≤ Ca ≤ 0.1%, traces ≤ Mg ≤ 0.8%, traces ≤ Nb ≤ 4.0%, traces ≤ V ≤ 4.0%, traces ≤ Ta ≤ 4.0%, traces ≤ Y ≤ 4.0%, the remainder being iron and impurities resulting from the production. The inclusion population, observed by image analysis on a polished surface of 650 mm² if the steel is in the form of a hot-formed part or a hot-rolled sheet and 800 mm² if the steel is in the form of a cold-rolled sheet, does not comprise non-metal inclusions of an equivalent diameter greater than 10 μm. The invention also relates to a product created from said steel, such as a metal sheet or strip, and to the manufacturing method thereof.
(FR) Acier, dont la composition est, en pourcentages pondéraux : 10,0% ≤ Ni ≤ 24,5%; 1,0% ≤ Mo ≤ 12,0%; 1,0% ≤ Co ≤ 18,0%; 14,0% ≤ Mo + Co + Si + Mn + Cu + W + V + Nb + Zr + Y + Ta + Cr + C + Al + B + Ti + N ≤ 29,0%; 21,5% ≤ Ni + Co + Mo ≤ 40,0%; traces ≤ Al ≤ 4,0%; traces ≤ Ti ≤ 0,1%; traces ≤ N ≤ 0,010%; traces ≤ Si ≤ 4,0%; traces ≤ Mn ≤ 13,0%; traces ≤ C ≤ 0,03%; traces ≤ S ≤ 0,0020%; traces ≤ P ≤ 0,005%; traces ≤ B ≤ 0,01%; traces ≤ H ≤ 0,0005%; traces ≤ O ≤ 0,03%; traces ≤ Cr ≤ 5,0%; traces ≤ Cu ≤ 4,0%; traces ≤ W ≤ 6,0%; traces ≤ Zr ≤ 4,0%; traces ≤ Ca ≤ 0,1%; traces ≤ Mg ≤ 0,8%; traces ≤ Nb ≤ 4,0%; traces ≤ V ≤ 4,0%; traces ≤ Ta ≤ 4,0%; traces ≤ Y ≤ 4,0%; le reste étant du fer et des impuretés résultant de l'élaboration, et la population inclusionnaire, observée par analyse d'image sur une surface polie de 650 mm² si l'acier est sous forme d'une pièce transformée à chaud ou d'une tôle laminée à chaud, et de 800 mm² si l'acier est sous forme d'une tôle laminée à froid, ne comporte pas d'inclusions non- métalliques de diamètre équivalent supérieur à 10 μm. Produit réalisé en cet acier tel qu'une tôle ou une bande, et son procédé de fabrication.
