摘要：The high strength galvanized steel plate has maximum tensile strength to be atleast 900 MPa and come the alloyed zinc hot dip galvanized layer base material steel discsurface of self-forming and contain C, Si, Mn, P, S, Al, N, O in scheduled amount, andremainder includes iron and inevitable impurity. For the structure in base material steelplate, retained austenite is limited to the fraction no more than 8% volume %; Stiffnessbetween the 2% and 98% of kurtosis (K*) hardness distribution, which is not more than, islower than 0.30; The base material steel plate 0. of the base material steel disc of thesuperficial layer of the Vickers hardness of the ratio and above-mentioned Vickershardness in 1/4 thickness35-0.On 70, iron is by 8-12% mass % in alloyed hot-dip zinclayers.
