Abstract:
(EN) 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 0.050% 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 tensile strength of 420-540 MPa, an elongation of 5% or more, a yield elongation of 3% or less, and a Δr of -0.50 to 0.10. (1): [N as BN]/[N] > 0.5
(FR) La présente invention concerne une tôle d'acier destinée à une boîte deux pièces étant caractérisée en ce qu'elle contient, en % en masse, pas moins de 0,010 % mais moins de 0,050 % de C, pas plus de 0,04 % de Si, pas moins de 0,10 % mais moins de 0,40 % de Mn, pas plus de 0,02 % de P, pas plus de 0,020 % de S, plus de 0,030 % mais pas plus de 0,100 % d'Al, pas moins de 0,0005 % mais moins de 0,0030 % de N, et de 0,0005 à 0,0030 % de B, la partie restante étant du Fe et des impuretés éventuelles, la quantité de N ([N étant BN]) existant en tant que BN et la quantité totale de N ([N]) satisfaisant à la formule mathématique (1), et la tôle d'acier a une résistance à la traction de 420 à 540 MPa, un allongement supérieur ou égal à 5 %, un allongement à la rupture inférieur ou égal à 3 %, et un Δr de -0,50 à 0,10. (1): [N étant BN]/[N] > 0,5
