Alloy 400 is a single phase, solid-solution alloy that offers superior resistance to many corrosive environments over a temperature range from sub-zero to 426°C. Alloy 400 has been widely used in many applications but has been particularly useful in marine and chemical processing. Typical applications include valves; pumps and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks; crude petroleum stills, process vessels and piping; boiler feedwater heaters and heat exchangers; and deaerating heaters.

Alloy 400 can be welded to itself or dissimilar metals by utilizing conventional welding processes. These include:

  • conventional or hot wire GTAW (TIG), plasma arc, GMAW (MIG/MAG) and SMAW (MMA).

The choice of welding product is dependent upon the materials being welded and the environment in which it occurs.
