摘要： The invention relates to a method for producing band-shaped steel for components which are produced by drawing and ironing. The invention also relates to a steel band which can be drawn or ironed and which has been produced by the inventive method. The hot strip is cold-worked in one or more steps at a ratio of the cold roll of at least 86%. Furthermore, at least one side of the band material is provided with a galvanically produced coating containing Ni, Co, Cu, Fe, Sn, In, Pd, Bi and/or the alloys thereof or with a roll-bonded coating containing Cu and/or brass and/or the alloys thereof. The aim of the invention is to carry out the inventive method with the fewest processing steps possible and with low production costs. The method therefore comprises the steps: etching, cold rolling in one or two steps, annealing the coiled band (coil-annealing), optionally rerolling the band. The hot strip preferably contains boron with a percentile of 0.0013 and 0.0060 percent by weight, whereby the weight ratio of boron to nitrogen amounts to 0.5 to 2.5.

摘要翻译： 本发明涉及一种用于制造通过拉丝和熨烫制造的部件用带状钢的方法。 本发明还涉及一种可以拉制或熨烫并且通过本发明方法生产的钢带。 热轧带材以一个或多个步骤进行冷加工，其冷轧比至少为86％。 此外，带材的至少一侧设有含有Ni，Co，Cu，Fe，Sn，In，Pd，Bi和/或其合金的电镀产品，或者与含有Cu和/ 或黄铜和/或其合金。 本发明的目的是以尽可能少的加工步骤和低的生产成本实现本发明的方法。 因此，该方法包括以下步骤：在一个或两个步骤中蚀刻，冷轧，退火卷绕带（线圈退火），可选地重新卷绕带。 热带优选含有百分位数为0.0013和0.0060重量％的硼，其中硼与氮的重量比为0.5-2.5。
