A1
Abstract:
To provide a hot dip Zn-Al based alloy plated steel product which exhibits high
corrosion resistance and is excellent in the bending workability of its plating
layer, and a method for producing the plated steel product. Provided are a hot
dip Zn-Al based alloy plated steel product is excellent in the bending workability,
and characterized in that it has a plating layer having such a chemical composition,
in mass %, that Al: 25 to 85 %, one or two of Cr and Mn: 0.05 to 5 %, Si: 0.5 to 10 % of the
content of Al, and the balance: Zn and inevitable impurities, and an average value
of spangle sizes on the surface of the plating is 0.5 mm or more; and a method for
producing the plated steel product.
