Title: STEEL SHEET FOR TWO-PIECE CAN AND PRODUCTION METHOD THEREFOR
Abstract:
The steel sheet for a two-piece can according to the present invention is characterized by containing, in mass%, not less than 0.010% but less than 0.030% of C, not more than 0.04% of Si, not less than 0.10% but less than 0.40% of Mn, not more than 0.02% of P, not more than 0.020% of S, more than 0.030% but not more than 0.100% of Al, not less than 0.0005% but less than 0.0030% of N, and 0.0005-0.0030% of B, the remaining portion being Fe and incidental impurities, wherein the amount of N ([N as BN]) existing as BN and the total amount of N ([N]) satisfy mathematical formula (1), and the steel sheet has a yield point of more than 280 MPa but less than 420 MPa, a yield elongation of 3% or less, and a Δr of -0.30 to 0.20. (1): [N as BN]/[N] > 0.5
