ASK:
ANSWER:HX340BD is a steel grade in European standard EN10346 ,HX340BD 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 HX340BD is 1.0945.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HX340BD+Z means hot dip zinc coated, structural material steel.
HX340BD+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX340BD+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX340BD+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX340BD+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX340BD+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HX340BD+Z steel mechanical property:
Yield strength should be 340-400MPa
Tensile strength should be 440-520MPa
Elongation A80 should be not less than 24%
Bake hardenning-index BH2 should be not less than 30MPa
