Abstract: A method for producing a corrosion resistant metal substrate and corrosion resistant metal substrate provided thereby. The method involves forming a plated substrate including a metal substrate provided with a nickel layer or with a nickel and cobalt layer followed by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, which is subsequently subjected to an annealing step in a reducing atmosphere to reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form a diffusion layer which contains nickel and molybdenum, and optionally cobalt.

Abstract: A process for manufacturing a containment device including: providing steel slab including (in wt. %) C: 0.05%-0.4%; Si: ?2.0%; Mn: ?2.0%; P: ?0.1%; N: ?200 ppm; remainder iron and inevitable impurities; hot rolling the slab to steel strip after reheating the slab, or utilizing the casting heat by hot-charging the slab, or by direct rolling the slab after casting, followed by cooling the strip to coiling temperature and coiling; cold rolling the strip at between 40 and 95% thickness reduction to form cold-rolled strip; continuous annealing by reheating to temperature above Ac1, homogenising at least 5 seconds, followed by rapid cooling; producing the device. The device has steel at least 10 vol. % martensite and/or bainite and reduced properties of anisotropy. Containment device manufactured by the process and producing isolation barrier material for high temperature and/or pressure sealing for containment devices are also disclosed.

Abstract: The invention relates to a double walled metal tube comprising a tubular roll formed metal band having a brazing layer between the metal layers of the tubular roll formed metal band, wherein the brazing layer consists of a copper alloy. According to the invention, the copper alloy is a copper-tin alloy, wherein the copper-tin alloy contains 3-12 wt % tin. The invention also relates to a metal band for forming such a double walled metal tube and to a metal strip for producing such metal bands, and to a method of coating a metal band and strip.

Abstract: The invention relates to a method for producing improved cold-rolled band that is capable of being deep-drawn or ironed and that has a carbon content of less than 0.5 weight %. The invention also relates to a cold-rolled band that can be produced by such a method, and preferably used for producing cylindrical containers and, in particular, battery containers by deep-drawing or ironing. The band that is cold-rolled with a cold-rolling ratio ranging from 30 to 95% is subjected to a thermal treatment in an annealing furnace and to a—preferably galvanic—coating of at least one of the two band surfaces.

Abstract: The invention relates to a method for producing an electrolytically coated cold rolled strip, preferably for use in the production of battery sheaths. The cold rolled strip is provided with a cobalt or a cobalt alloy layer by an electrolytic method. The aim of the invention is to provide a battery sheath with low values for the electric contact resistance between the cathode substance of the battery and the inner surface of the battery sheath. To this end, organic substances m added to the electrolyte during coating that produce decomposition products, said decomposition produces and/or reaction products of said decomposition products with other components of the electrolytic bath being deposited on the strip material as a brittle layer along with the cobalt or the cobalt alloy.

Abstract: A battery sheath made of formed and cold-rolled sheet metal as well as a process for manufacturing the battery sheath are proposed. In the process, cold-rolled strip stock is provided on at least one side with a coating of Ni, Co, Fe, Sn, In, Pd, Bi or their alloys in an electroplating bath, e.g., a Watts-type bath. As an additional component, the electroplating bath contains electrically conductive particles such as carbon, carbon black, graphite, TiS2, TaS2, MoSi2. These particles are deposited on the base material during electroplating together with Ni, Co, Fe, Sn, In, Pd, Bi or their alloys. The sheet metal side with, for example, the carbon-containing electroplated coating faces preferably inwardly when the sheet is formed into a battery sheath. Batteries with battery sheaths produced in this manner exhibit reduced increase in internal resistance, even with prolonged storage, as compared to known batteries.

Abstract: 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.
