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.
