ANSWER:DX53D is a steel grade in European standard EN10346, DX53D is bending and profiling quality steel material, The material No. of DX53D is 1.0951. DX53D's Carbon composition content is less than 0.18%, it belongs to low carbon material, used for cold forming.
+ZA means Hot-dip Zinc-aluminium alloy coated, application of a Zinc-aluminium coating by immersing the prepared strip in a molten bath of zinc-aluminum-aluminium. The composition of the bath is approximately 5% aluminum, small amounts of mischmetal and the balance zinc. So DX53D+ZA means hot dip Zinc-aluminium coated, low carbon for cold forming, bending and profiling quality, Flat product steel.
DX53D+ZA material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
DX53D+ZA steel coating finish is N(Normal spangle) or M(Minimized spangle)
DX53D+ZA steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
DX53D+ZA steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
DX53D+ZA steel Coating mass are: ZA095, ZA130, ZA185, ZA200, ZA255, ZA300
DX53D+ZA steel mechanical property:
Yield strength should be between 140-260MPa
Tensile strength should be between 270-380MPa
Elongation A80 should be not less than 30%
