ASK:
ANSWER:HDT450F is a 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 is 1.0961.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HDT450F+Z means hot dip zinc coated, structural material steel.
HDT450F+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HDT450F+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HDT450F+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HDT450F+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HDT450F+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HDT450F+Z 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%
