Abstract (en)
[origin: WO2018073117A1] The invention relates to a steel strip, sheet or blank used for painted parts, wherein the steel strip, sheet or blank is optionally metallic coated. According to the invention the steel is an Ultra Low Carbon (ULC) steel type having a composition of (in weight%): C: max 0.007; Mn: max 1.2; Si: max 0.5; Al: max 0.1; P: max 0.15; S: 0.003-0.045; N: max 0.01; Ti, Nb, Mo: if Ti ≥ 0.005 and Nb ≥ 0.005: 0.06 ≤ 4Ti + 4Nb + 2Mo ≤ 0.60; otherwise 0.06 ≤ Ti+2Nb + 2Mo ≤ 0.60; and one or more of the optional elements: Cu: max 0.10; Cr: max 0.06; Ni: max 0.08; B: max 0.0015; V: max 0.01; Ca: max 0.01; Co: max 0.01; Sn: max 0.01; resulting in a delta Waviness ΔWsa ≤ 0,12 μm of the surface after the forming of the strip, sheet or blank.
