Aceroinoxidable----Nickel-copper alloy Monel 400
Nickel-copper alloy Monel four hundred Equivalents: UNS N04400/Alloy 400/Werkstoff a pair of 2.4360
Monel four hundred may be a nickel-copper alloy (about sixty seven nickel – twenty third Cu) that's proof against ocean water and steam at high temperatures additionally on salt and caustic solutions. Alloy four hundred may be a solution alloy which will solely be hardened by cold operating. This metal exhibits characteristics like sensible corrosion resistance, sensible weldability and high strength. a coffee corrosion rate in quickly flowing briny or brine combined with wonderful resistance to stress-corrosion cracking in most freshwaters, and its resistance to a range of corrosive conditions diode to its wide use in marine applications and different non-oxidizing chloride solutions. This metal is especially proof against hydrochloric and hydrofluoric acids after they ar de-aerated. As would be expected from its high copper content, alloy four hundred is quickly attacked by acid and ammonia systems.
Monel four hundred has nice mechanical properties at subzero temperatures, is utilized in temperatures up to 1000° F, and its freezing point is 2370-2460° F. However, alloy four hundred is low in strength within the tempered condition thus, a range of tempers is also accustomed increase the strength.
In what forms is Monel four hundred Available?

Corrosion Resistant Monel four hundred
Alloy four hundred is nearly resistant to chloride particle stress corrosion cracking in typical environments. Generally, its corrosion resistance is incredibly sensible in reducing environments, however poor in oxidizing conditions. it's not helpful in oxidizing acids, like acid and azotic. notwithstanding, it's proof against most alkalis, salts, waters, food product, organic substances and part conditions at traditional and elevated temperatures.
This metal is attacked in sulfur-bearing gases higher than roughly 700° F and liquified sulfur attacks the alloy at temperatures over roughly 500° F.
Monel four hundred offers concerning identical corrosion resistance as nickel however with higher most operating pressures and temperatures and at a lower value attributable to its superior ability to be machined.
In what applications is Monel four hundred used?
Marine engineering
Chemical and organic compound process instrumentality
Gasoline and fresh tanks
Crude crude oil stills
De-aerating heaters
Boiler feed water heaters and different heat exchangers
Valves, pumps, shafts, fittings, and fasteners
Industrial heat exchangers
Chlorinated solvents
Crude oil distillation towers
