ANSWER:HX220BD is a steel grade in European standard EN10346 ,HX220BD is bake hardening quality steel material (the steel exhibiting an increase in proof strength following heating in the region of 170 °C for 20 min ), The material No. of HX220BD is 1.0919.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HX220BD+Z means hot dip zinc coated, structural material steel.
HX220BD+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX220BD+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX220BD+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX220BD+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX220BD+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HX220BD+Z steel mechanical property:
Yield strength should be 220-280MPa
Tensile strength should be 320-400MPa
Elongation A80 should be not less than 32%
R90 should be not less than 1.2
N90 should be not less than 0.15
Bake hardenning-index BH2 should be not less than 35MPa
