ASK:
ANSWER: HDT750C is a steel grade in European standard EN10346 ,HDT750C is multiphasephase hot rolled steel for cold forming,complex-phase quality steels material (the steel with multiphase 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.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HDT750C+Z means hot dip zinc coated, structural material steel.
HDT750C+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT750C+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT750C+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT750C+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT750C+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HDT750C+Z 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%
