ASK:
ANSWER:HCT590X is a steel grade in European standard EN10346 ,HCT590X is dual-phase quality steel material for cold forming (the steel consisting of mainly ferrite and martensite and possible bainite as a complementary phase ), The material No. of HCT590X is 1.0996.
+Z means hot dip Zinc coating. The zinc content is at least 99% . So HCT590X+Z means hot dip zinc coated, structural material steel.
HCT590X+Z material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HCT590X+Z steel coating finish is N(Normal spangle) or M(Minimized spangle)
HCT590X+Z steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HCT590X+Z steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HCT590X+Z steel Coating mass are: Z60/Z80/Z100/Z410/Z200/Z225/Z275/Z350/Z450/Z600
HCT590X+Z steel mechanical property:
Yield strength should be 330-430MPa
Tensile strength should be not less than 590MPa
Elongation A80 should be not less than 20%
Strain hardening exponent should be not less than 0.14
Bake hardening index BH2 should be mot than than 30MPa
