Document Type and Number:
WIPO Patent Application WO/2001/011100
Kind Code:
A1
Abstract:
A Zn-Al-Mg-Si alloy plated steel product having excellent corrosion resistance characterized in that the alloy coating layer thereof comprises, in mass %, 45 to 70 % of Al, 3 % or more and less than 10 % of Mg, 3 % or more and less than 10 % of Si, the balance of the layer being Zn and inevitable impurities, provided that Al/Zn is 0.89 to 2.75, and contains a Mg¿2?Si phase in a bulk form; and a Zn-Al-Mg-Si alloy plated steel product having excellent corrosion resistance characterized in that the alloy coating layer thereof comprises, in mass %, 45 to 70 % of Al, 1 % or more and less than 5 % of Mg, 0.5 % or more and less than 3 % of Si, the balance of the layer being Zn and inevitable impurities, provided that Al/Zn is 0.89 to 2.75, and contains a Mg¿2?Si phase in a flake form.
