Monel Alloy 400

Monel Alloy 400 - A Solid Solution Alloy

Monel alloy 400 is a solid solution alloy that can be hardened by cold working. It proves to be strong and rugged over at high temperatures along with exceptional resistance to a lot of corrosive environments. Alloy 400 is utilised vastly in various fields, like marine and chemical processing. It is used in applications like marine fixtures and fasteners and crude petroleum stills. Supreme Engineering Limited can be approached if you're looking for Monel alloy 400 suppliers and Monel alloy 400 manufacturers.

It is also used in various other applications like valves and pumps, electrical and electronic components, gasoline and fresh water tanks, process vessels and piping, crude petroleum stills, heat exchangers and boiler feedwater heaters. Curie temperature is within the ambient range and is affected by variations in chemical composition. Some heats are magnetic at room temperature.

Features of Monel alloy 400:

  • Exceptional strength and corrosion resistance in various media like sulfuric acid and sea water.
  • Strong and rugged over a wide temperature range.
  • Good resistance to corrosive environment.
  • Good mechanical properties at subzero temperatures.
