ANSWER:HX500LAD+ZF is a hot dip Zinc-iron coated steel grade in European standard EN10346 ,HX500LAD+ZF is low alloy/micro-alloyed quality steel material (the steel containing one or more of alloying elements Nb, Ti and V achieve required proof strength levels ), The material No. of HX500LAD is 1.0991+ZF.
+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 HX500LAD+ZF means hot dip zinc-iron coated, cold forming material steel with high proof strength .
HX500LAD+ZF material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX500LAD+ZF steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX500LAD+ZF steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX500LAD+ZF steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX500LAD+ZF steel Coating mass are: ZF100, ZF120
HX500LAD+ZF steel mechanical property:
Proof strength should be 500-620MPa
Tensile strength should be 530-690MPa
Elongation A80 should be not less than 13%
