Definition
This European Standard specifies requirements for continuously hot-dip coated strip and sheet made of low carbon steels for cold-forming coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminum alloy (ZA), aluminum-zinc alloy (AZ), and aluminum-silicon alloy (AS) with thicknesses of 0,35 mm to 3,0 mm unless otherwise agreed. The thickness is the final thickness of the delivered product after coating.
Classification
They are classified in accordance with their increasing suitability for cold forming as follows:
DX51D: bending and profiling quality;
DX52D: drawing quality;
DX53D: deep drawing quality; DX54D:
special deep drawing quality;
DX55D: special deep drawing quality, (only +AS), heat resistance up to 800 °C;
DX56D: extra deep drawing quality;
DX57D: super deep drawing quality
