Cold Working and Welding Processes
Cold Working Performance: It exhibits good plasticity in the solution-treated state, allowing for conventional cold forming operations such as cold bending and cold stamping. However, work hardening is significant; for deep forming, intermediate annealing may be necessary to restore plasticity.
Recommended Methods: Conventional methods such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding can be used for joining.
Welding Consumables Selection: Nickel-based welding wire with a composition matching the base metal should be selected to ensure weld performance. AWS ERNiCr-3 (such as Inconel 82) is recommended.
Operating Points: The weld area must be cleaned before welding, and the interpass temperature should be controlled to avoid excessive heat input. Post-weld solution treatment is generally recommended to restore the microstructure and corrosion resistance of the heat-affected zone.
Using Incoloy 890 alloy bars, you can obtain high-strength, corrosion-resistant solutions that outperform conventional materials in extreme high-temperature and corrosive environments. Please contact us for more information.
