STEEL SHEET WITH EXCELLENT AGING RESISTANCE, AND METHOD FOR PRODUCING SAME
A steel sheet with an excellent aging resistance property and a method for producing the same are provided. The steel sheet has a composition containing 0.015% to 0.05% C, less than 0.10% Si, 0.1% to 2.0% Mn, 0.20% or less P, 0.1% or less S, 0.01% to 0.10% Al, 0.005% or less N, and 0.06% to 0.5% Ti...

| description | A steel sheet with an excellent aging resistance property and a method for producing the same are provided. The steel sheet has a composition containing 0.015% to 0.05% C, less than 0.10% Si, 0.1% to 2.0% Mn, 0.20% or less P, 0.1% or less S, 0.01% to 0.10% Al, 0.005% or less N, and 0.06% to 0.5% Ti in percent by mass, C and Ti satisfying the inequality Ti*/C ‰¥ 4, where Ti* (mass percent) = Ti - 3.4N and Ti, C, and N represent the content (mass percent) of each element. The steel sheet has a microstructure which contains a ferrite phase as a base, in which the average grain diameter of the ferrite phase is 7 µm or more, and in which the ratio d L /d t of the rolling-direction average grain diameter d L to thickness-wise average grain diameter d t of the ferrite phase is 1.1 or more. This allows the steel sheet to have an excellent aging resistance property. |
