ASK:
ANSWER:HDT450F+ZF is a hot dip Zinc-iron coated steel grade in European standard EN10346 ,HDT450F 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 HDT450F+ZF is 1.0961+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 HDT450F+ZF means hot dip zinc-iron coated,multiphasephase quality steel material for cold forming .
HDT450F+ZF material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT450F+ZF steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT450F+ZF steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT450F+ZF steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT450F+ZF steel Coating mass are: ZF100, ZF120
HDT450F+ZF steel mechanical property:
Yield strength should be 300-420MPa
Tensile strength should be not less than 450MPa
Elongation A80 should be not less than 24%
