    • There is provided a high-strength steel plate having adcular ferrite and bainite as a main mi- crostructure and an austenite/martensite (M & A) as a second phase under the control of a cooling rate above the austenite transformation temperature. The high-strength steel plate comprises: carbon (C): 0.03 to 0.10 wt%, silicon (Si): 0.1 to 0.4 wt%, manganese (Mn): 1.8 wt% or less, nickel (Ni): 1.0 wt% or less, titanium (Ti): 0.005 to 0.03 wt%, niobium (Nb): 0.02 to 0.10 wt%, aluminum (Al): 0.01 to 0.05 wt%, calcium (Ca): 0.006 wt% or less, nitrogen (N): 0.001 to 0.006 wt%, phosphorus (P): 0.02 wt% or less, sulfur (S): 0.005 wt% or less, and the balance of iron (Fe) and other inevitable impurities. The method for manufacturing a high-strength steel plate may be useful to economically and effectively manufacture a high strength steel, which is able to secure excellent properties svch as high strength and high toughness since the acicular ferrite and bainite may be effectively formed without adding expensive elements such as molybdenum (Mo).
    • 在高于奥氏体相变温度的冷却速度的控制下,提供了具有作为主要微结构的铁素体和贝氏体作为第二相的高强度钢板和奥氏体/马氏体(M&A)。 高强度钢板包括:碳(C):0.03〜0.10重量%,硅(Si):0.1〜0.4重量%,锰(Mn):1.8重量%以下,镍(Ni):1.0重量% 较少,钛(Ti):0.005〜0.03重量%,铌(Nb):0.02〜0.10重量%,铝(Al):0.01〜0.05重量%,钙(Ca):0.006重量%以下,氮(N) :0.001〜0.006重量%,磷(P):0.02重量%以下,硫(S):0.005重量%以下,余量由铁(Fe)等不可避免的杂质构成。 制造高强度钢板的方法可有效地经济有效地制造高强度钢,其能够确保优异的性能,因为高强度和高韧性,因为可以有效地形成针状铁素体和贝氏体而不增加昂贵的 元素如钼(Mo)。
