Title (EN) PROCESS FOR PRODUCING HIGH-STRENGTH COLD-ROLLED STEEL PLATE FOR PRESS WORKING
(FR) PROCEDE DE PREPARATION DE TOLE D"ACIER LAMINEE A FROID A HAUTE RESISTANCE POUR LE TRAVAIL A LA PRESSE
Abstract: front page image
(EN)A process for producing a high-strength cold-rolled steel plate for press working having a tensile strength of 35-45 kg/mm2 and a yield ratio of 0.4-0.6, which comprises hot-rolling steel comprising 0.005-0.080% of C, not more than 0.30% of Si, 1.6-3.5% of Mn, 0.02-0.08% of sol. A1, 0.005-0.020% of N, and balance of Fe and unavoidable impurities, and, after cold-rolling, annealing at 660-750 C for not shorter than 30 minutes.
(FR)Procede de preparation de tole d"acier laminee a froid a haute resistance pour le travail a la presse ayant une resistance a la traction de 35-45 kg/m2 et un module d"elasticite de 0,4-0,6 qui comprend un acier lamine a chaud contenant 0,0005-0,080%, de C, pas plus de 0,30% de Si, 1,6-3,5% de Mn, 0,020-0,08% d"A1, 0,005-0,02% de N et le complement en Fe et impuretes inevitables et apres laminage a froid, l"on recuit a 660-750 C pendant au moins 30 minutes.
