Steel Sheet And Method For Producing Same
Abstract: This steel sheet has a specific chemical composition and metal structure. In the crystalline orientation distribution function of the aggregate structure at a position of 1/4 the plate thickness, when A is the maximum value of pole density at F = 20° to 60° and f1 = 30° to 90° in the f2 = 45° cross section and B is the maximum value of pole density at F = 120° to 60° and f1 = 30° to 90° in the f2 = 45° cross section, the ratio A/B is 1.50 or less and the total of the maximum value A and the maximum value B is 6.00 or less. Tensile strength is 1030 MPa or greater.
