Monel 400

Monel 400

Monel 400 is a nickel-copper alloy (about 67% Ni – 23% Cu) that is resistant to seawater and steam at high temperatures as well as to salt and caustic solutions. Alloy 400 is a solid solution alloy that can only be hardened by cold working. This nickel alloy exhibits characteristics like good corrosion resistance, good weldability, and high strength.

Application Industries

These materials are not a single material but the name for a family of corrosion resistant steels. Like many scientific breakthroughs, the origins of stainless steel lies in a lucky accident. From the smallest part of the zipper to the largest building skyscraper.
Metal fabrication is widely used across various industrial sectors such as mining, construction, manufacturing, shipbuilding, automotive, aerospace, and energy.
