Process for the production of nickel alloys with optimized strip weldability

摘要

The invention relates to processes for the production of nickel alloys with optimized strip weldability (TIG without additive) from an alloy of the following composition (in% by weight): C max. 0.05% Co max. 2.5% Ni residue, in particular 35-75.5% Mn max. 1.0% Si max. 0.5% Mo 2 - 17% P max. 0.2% S max. 0.05% Cu max. 3.0% Fe 0 - 38.0% Ti 0 - 2.5% Al 0 - 0.5% Cr 14 - 25% V max. 0.5% W to 3.5% Mg to 0.1% - by melting the alloy open and pouring it into blocks, - subjecting the blocks to at least one heat treatment as required, - subsequently melting the blocks by ESC at least once, - the remelted block thus obtained is subjected to at least one heat treatment as required, the block is subjected to at least one cold and / or hot forming operation until strip material of predeterminable material thickness is present, - the strip material is divided into strip strips in defined lengths / widths.
