ANSWER:HX500LAD+ZM is a hot dip Zinc-iron coated steel grade in European standard EN10346 ,HX500LAD+ZM 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+ZM.
+ZM means Hot-dip Zinc-magnesium alloy coated, application of a Zinc-magnesium coating by immersing the prepared strip in a molten bath of zinc-aluminum-magnesium. The composition of the bath is sum of aluminium and magnesium from 1.5%-8%, containing minimum of 0.2% magnesium and the balance zinc. So HX500LAD+ZM means hot dip Zinc-magnesium coated,cold forming quality material with low alloy/micro-alloyed quality.
HX500LAD+ZM material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX500LAD+ZM steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX500LAD+ZM steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX500LAD+ZM steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX500LAD+ZM steel Coating mass are: ZF100, ZF120
HX500LAD+ZM steel mechanical property:
Proof strength should be 500-620MPa
Tensile strength should be 530-690MPa
