Abstract: The invention relates to methods for the manufacture of nickel alloys having optimized strip weldability (TIG without filler) from an alloy of the following composition (in wt%): C max. 0.05%, Co max. 2.5%, Ni the rest, especially >35 - 75.5%, Mn max. 1.0%, Si max. 0.5%, Mo >2 to 23%, P max. 0.2%, S max. 0.05%, N up to 0.2%, Cu 1.0%, Fe >0 to <7.0%, Ti >0 to <2.5%, Al >0 to 0.5%, Cr >14 to <25%, V max. 0.5%, W up to 3.5%, Mg up to 0.2%, Ca up to 0.02%, in that the alloy is smelted openly and cast as ingots, the ingots are subjected if necessary to at least one heat treatment, the ingots are then remelted at least one time by electroslag refining, the remelted ingot obtained in this way is subjected if necessary to at least one heat treatment, the ingot is subjected to at least one cold and/or hot deformation cycle, until strip material of predeterminable material thickness exists, the strip material is subdivided into strip sections of defined lengths/widths.

Abstract: A method for producing a metal film composed of an alloy having more than 50% nickel (a) melts the alloy in amounts of more than one ton in a vacuum induction furnace, or openly in an induction or arc furnace, followed by treatment in a VOD or VLF installation, (b) the alloy is cast into blocks, electrodes or as continuous casting to form a pre-product, (c) the pre-product is annealed if necessary at temperatures between 800° C.-1350° C. for 1-300 hours under air or protective gas, and (d) hot rolled between 1300° C.-600° C. to reduce the thickness of the starting material by a factor of 1.

Abstract: A method for producing a metal film from an alloy having more than 50% nickel includes the following steps: (a) the alloy is melted in volumes of more than one ton in a vacuum induction furnace, or open in an induction or arc furnace, followed by treatment in a VOD or VLF system, (b) the alloy is then poured off in blocks, electrodes or as continuous casting to form a pre-product, followed by single or multiple re-melting by VAR and/or ESU (c) the pre-product is then annealed between 800 and 1350° C. for 1-300 hours under air or protection gas, (d) the pre-product is then hot-formed between 1300 and 600° C. to reduce the thickness of the input material by the factor 1.
