ANSWER:DX56D is a steel grade in European standard EN10346, DX56D is bending and profiling quality steel material, The material No. of DX56D is 1.0963. DX56D's Carbon composition content is less than 0.18%, it belongs to low carbon material, used for cold forming.
+AZ means Application of an Aluminium-zinc coating by immersing the prepared strip in a molten bath of Aluminium-zinc-silicon. The composition of the bath is 55% of aluminium,1.6% of silicon and the balance zinc So DX56D+AZ means hot dip Aluminium-Zinc coated, low carbon for cold forming, bending and profiling quality, Flat product steel.
DX56D+AZ material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
DX56D+AZ steel coating finish is N(Normal spangle) or M(Minimized spangle)
DX56D+AZ steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
DX56D+AZ steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
DX56D+AZ steel Coating mass are: AZ100, AZ150, AZ185
DX56D+AZ steel mechanical property:
Yield strength should be between 120-180MPa
Tensile strength should be between 260-350MPa
Elongation A80 should be not less than 39%
Plastic strain ratio R90 should be not less than 1.9
Strain hardening exponent N90 should be not less than 0.21
