ASK:
ANSWER:HDT750C is a steel grade in European standard EN10346 ,HDT750C is multi phase hot rolled steel for cold forming,complex-phase quality steels material (the steel with multi phase microstructure containing mainly bainite, ferrite, whereas martensite, tempered martensite, retained austenite and pearlite may be present as additonal phases), The material No. of HDT750C is 1.0956.
+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 HDT750C+ZF means hot dip zinc-iron coated,multiphase quality steel material for cold forming .
HDT750C+ZF material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT750C+ZF steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT750C+ZF steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT750C+ZF steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT750C+ZF steel Coating mass are: ZF100, ZF120
HDT750C+ZF steel mechanical property:
Yield strength should be 620-760MPa
Tensile strength should be not less than 750MPa
Elongation A80 should be not less than 10%
