ASK:
ANSWER:HX300YD is a steel grade in European standard EN10346 ,HX300YD is high strength interstitial free quality steel material (the steel whose composition is controlled to achieve improved plastic strain ratio r and strain hardening exponent n values), The material No. of HX300YD is 1.0927.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HX300YD+Z means hot dip zinc coated, structural material steel.
HX300YD+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HX300YD+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HX300YD+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HX300YD+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HX300YD+Z steel mechanical property:
Yield strength should be 300-360MPa
Tensile strength should be 390-470MPa
Elongation A80 should be not less than 27%
R90 should be not less than 1.3
N90 should be not less than 0.15
