Monel 400
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.
