Monel four hundred may be a nickel-copper alloy (about sixty seven metal – twenty third Cu) that's proof against ocean water and steam at high temperatures likewise on salt and caustic solutions. Alloy four hundred may be a solution alloy that may solely be hardened by cold operating. This alloy exhibits characteristics like sensible corrosion resistance, sensible weldability and high strength. a coffee corrosion rate in chop-chop flowing salt or H2O combined with glorious resistance to stress-corrosion cracking in most freshwaters, and its resistance to a range of corrosive conditions light-emitting diode to its wide use in marine applications and alternative non-oxidizing chloride solutions. This alloy is especially proof against hydrochloric and hydrofluoric acids once they square measure de-aerated. As would be expected from its high copper content, alloy four hundred is chop-chop attacked by acid and ammonia systems.
Monel four hundred has nice mechanical properties at subzero temperatures, will be utilized in temperatures up to 1000° F, and its temperature is 2370-2460° F. However, alloy four hundred is low in strength within the toughened condition therefore, a range of tempers could also be wont to increase the strength.

Alloy four hundred object
*Alloy four hundred is slightly magnetic at temperature.
*This alloy encompasses a long history of use as a corrosion resistant material, chemical analysis back to the first twentieth century once it absolutely was developed as a shot to use a high copper content nickel ore. The nickel and copper contents of the ore were within the approximate quantitative relation that is currently formally given for the alloy.
