The Monel400 bar is a nickel-copper alloy (about 67% ni-23% Cu) that is resistant to seawater and steam as well as salt and corrosive solutions at high temperatures. Alloy 400 is a solid solution of gold that can only be hardened by cold work. The nickel alloy has good corrosion resistance, good weldability and high strength

When alloying elements are added to steel, iron and carbon, the basic components of steel, interact with alloying elements. The purpose of steel alloying is to improve the microstructure and properties of steel by the interaction of alloying elements with iron and carbon and the influence on the phase diagram of iron and carbon and the heat treatment of steel.
