ANSWER:HDT580F+ZM is a hot dip Zinc-magnesium coated steel grade in European standard EN10346 ,HDT580F+ZM is multiphasephase hot rolled steel for cold forming,ferritic-bainitic quality steels material (the steel with a matrix of ferrite or strengthened ferrite containing bainite or strengthened bainite), The material No. of HDT580F+ZM is 1.0994+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 HDT580F+ZM means hot dip zinc-magnesium coated, multiphasephase hot rolled steel for cold forming .
HDT580F+ZM material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT580F+ZM steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT580F+ZM steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT580F+ZM steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT580F+ZM steel Coating mass are:
ZM060,ZM070,ZM080,ZM090,ZM100,ZM120,ZM130,ZM140,ZM150,ZM160,ZM175,ZM190,ZM200,ZM250,ZM300,ZM310,ZM350,ZM430,
HDT580F+ZM steel mechanical property:
Yield strength should be 460-620MPa
Tensile strength should be not less than 580MPa
Elongation A80 should be not less than 15%
