ANSWER:HDT580X is a steel grade in European standard EN10346 ,HDT580X is multi phase hot rolled steel for cold forming,dual-phase quality steels material (the steel consisting of mainly ferrite and martensite and possible bainite as a complementary phase), The material No. of HDT580X is 1.0936.
+ZF means hot dip Zinc-iron coating. The zinc content of the bath is at least 99%, or the annealing produces and iron-zinc coating with an iron content of normally 8%-12%. So HDT580X+ZF means hot dip zinc-iron coated,multiphase quality steel material for cold forming .
HDT580X+ZF material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT580X+ZF steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT580X+ZF steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT580X+ZF steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT580X+ZF steel Coating mass are: ZF100, ZF120
HDT580X+ZF steel mechanical property:
Yield strength should be 330-450MPa
Tensile strength should be not less than 580MPa
Elongation A80 should be not less than 19%
Strain hardening exponent should be not less than 0.13
