  • Patent number: 10988829
    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.
