摘要： In an embodiment of a steel sheet having high Young's modulus, the steel can include in terms of mass %, e.g., C: 0.0005 to 0.30%, Si: 2.3% or less, Mn: 2.7 to 5.0%, P: 0.15% or less, 0.015% or less, Mo: 0.15 to 1.5%, B: 0.0006 to 0.01%, and Al: 0.15% or less, with the remainder being Fe and unavoidable impurities. One or both of {110} pole density and {110} pole density in the ⅛ sheet thickness layer can be 10 or more, and a Young's modulus in a rolling direction can be more than 230 GPa. Other embodiments can include, e.g., Mn: 0.1 to 5.0%, N: 0.01% or less, and one or more of Mo: 0.005 to 1.5%, Nb: 0.005 to 0.20%, Ti: at least 48/14×N (mass %) and 0.2% or less, and B: 0.0001 to 0.01%, at a total content of 0.015 to 1.91 mass %.

摘要： The invention provides a cold-rolled steel sheet excellent in paint bake hardenability and ordinary-temperature non-aging property comprising, in mass %, C: 0.0005-0.0040%, Si: 0.8% or less, Mn: 2.2% or less, S: 0.0005-0.009%, Cr: 0.4-1.3%, O: 0.003-0.020%, P: 0.045-0.12%, B: 0.0002-0.0010%, Al: 0.008% or less, N: 0.001-0.007%, and a balance of Fe and unavoidable impurities. Ultra-low-carbon steel retaining solute N and containing added Cr, P, B and O is used to produce hot-rolled and cold-rolled steel sheet and hot-dip galvanized cold-rolled steel sheet that exhibit both high paint bake hardenability and ordinary-temperature non-aging property.
