ANSWER:HCT980X is a steel grade in European standard EN10346, HCT980X+ZA 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 HCT980X is 1.0944.
+ZA means Hot-dip Zinc-aluminium alloy coated, application of a Zinc-aluminium coating by immersing the prepared strip in a molten bath of zinc-aluminum-aluminium. The composition of the bath is approximately 5% aluminum, small amounts of mischmetal and the balance zinc. So HCT980X+ZA means hot dip Zinc-aluminium coated, dual-phase quality steel material for cold forming.
HCT980X+ZA material steel have coil, strip, sheet condition, thickness is from 0.2mm-3mm.
HCT980X+ZA steel coating finish is N(Normal spangle) or M(Minimized spangle)
HCT980X+ZA steel Surface quality A (As coated surface) , B(Improved surface), C(Best quality surface)
HCT980X+ZA steel Surface treatment C (chemically passivated) , O (oiled), CO (chemically passivated and oiled) , P (phosphate) , PO (phosphate and oiled), S (sealed)
HCT980X+ZA steel Coating mass are: ZA095, ZA130, ZA185, ZA200, ZA255, ZA300
HCT980X+ZA steel mechanical property:
Yield strength should be 590-740MPa
Tensile strength should be not less than 980MPa
Elongation A80 should be not less than 10%
Bake hardening index BH2 should be mot than than 30MPa
