Title:
PLATED STEEL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/281729
Kind Code:
A1
Abstract:
A plated steel material which has a plating layer on the surface of a steel material, and which is characterized by satisfying formula 1 (0 ≤ Cr + Ti + Ni + Co + V + Nb + Cu + Mn ≤ 0.25) and formula 2 (0 ≤ Sr + Sb + Pb + B + Li + Zr + Mo + W + Ag + P ≤ 0.50), and also satisfying formula 3 (I(MgZn2(41.31°))/IΣ(MgZn2) ≤ 0.265) and formula 6 (0.150 ≤ \{I(MgZn2(20.79°)) + I(MgZn2(42.24°))\}/IΣ(MgZn2)) with respect to the X-ray diffraction pattern of the surface of the plating layer as determined using a Cu-Kα ray with the X-ray output at 40 kV and 150 mA.
