Fabrication
| Fabrication Process | Description |
| Hot Working | Hot worked in 648-1204°C temperature range. Hot working processes include extrusion, forging, and rolling. |
| Cold Working | Monel 400 has excellent ductility, thus suitable for process such as forming, bending, and drawing. |
| Welding | Monel 400 can be welded using a variety of processes. That includes gas tungsten arc welding (GTAW/TIG), gas metal arc welding (GMAW/MIG), and submerged arc welding (SAW). |
| Brazing | Techniques include furnace brazing, torch brazing, and induction brazing. |
| Soldering | Monel 400 can be soldered using appropriate fluxes and solders. |
| Heat Treatment | Monel 400 can be annealed at temperatures of 926-1038°C to relieve stress and increase ductility. Other heat treatment processes, such as precipitation hardening, are not applicable to Monel 400. |
