摘要： 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.
