Monel 400 is a nickel-copper alloy (about 67% Ni - 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. Monel 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. A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions. This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, monel 400 is rapidly attacked by nitric acid and ammonia systems.    Monel 400 has great mechanical properties at subzero temperatures, can be used in temperatures up to 1000° F, and its melting point is 2370-2460° F. However, monel 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.     Monel 400 Specification             Item Brand Chemical Composition (%) Monel 400 C Mn Si S Ni Fe Cu ≤0.3 ≤2.0 ≤0.5 ≤0.024 ≥63.0 ≤2.5 28.0~34.0 Standard Sheet/Plate Round bar/Wire Pipe Tube ASME SB-127 AMS 4544 QQ-N-281 ASME SB-164 ASME SB-564 AMS 4675 AMS 4730 AMS 4731 ASME SB-163 ASME SB-165 ASME SB-829 ASME SB-730 ASME SB-751 ASME SB-775 Alloy state Tensile strength Rm N/mm² Yield strength 0. 2N/mm² Elongation Status Monel 400 480 170 35 Solution treatment  stainless steel, sink strainer,fruit vegetable washing drain basket,kitchen tool,draining rack, draining basket.
