ASK:
ANSWER:HX420LAD is a steel grade in European standard EN10346 ,HX420LAD is low alloy/micro-alloyed quality steel material (the steel containning one or more of alloying elements Nb,Ti and V to achieve required proof strength levels ), The material No. of HX420LAD is 1.0935.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HX420LAD+Z means hot dip zinc coated, structural material steel.
HX420LAD+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX420LAD+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX420LAD+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX420LAD+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX420LAD+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HX420LAD+Z steel mechanical property:
Yield strength should be 420-520MPa
Tensile strength should be 470-590MPa
Elongation A80 should be not less than 17%
