摘要: A method for manufacturing a hot-rolled and coated steel sheet having a thickness between 1.8 mm and 5 mm, comprising providing a semi-product having a composition comprising: 0.04% ≤ C ≤ 0.38%, 0.40% ≤ Mn ≤ 3%, 0.005% ≤ Si ≤ 0.70%, 0.005% ≤ Al ≤ 0.1%, 0.001% ≤ Cr ≤ 2%, 0.001% ≤ Ni ≤ 2%, 0.001% ≤ Ti ≤ 0.2%, Nb ≤ 0.1%, B ≤ 0.010%, 0.0005% ≤ N ≤ 0.010%, 0.0001% ≤ S ≤ 0.05%, 0.0001% ≤ P ≤ 0.1%, Mo ≤ 0.65 %, W ≤ 0.30%, Ca ≤ 0.006%, hot-rolling with a final rolling temperature FRT, to obtain a hot-rolled steel product having a thickness between 1.8 mm and 5 mm, then cooling down to a coiling temperature Tcoil satisfying: 450°C ≤ Tcoil ≤ Tcoilmax with Tcoilmax=650-140×fγ, Tcoilmax being expressed in degrees Celsius and fy designating the austenite fraction just before the coiling, and coiling to obtain a hot-rolled steel substrate, pickling and coating the hot-rolled steel substrate with Al or an Al alloy by continuous hot-dipping in a bath, to obtain a hot-rolled and coated steel sheet comprising a hot-rolled steel sheet and an Al or an Al alloy coating, having a thickness comprised between 20 and 33 µm, on each side of the hot-rolled steel sheet.
