We are one of the top suppliers of machined and precision engineering products of titanium, nickel alloy, molybdenum, tantalum and some other advanced metal materials.

-- 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. 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. 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, alloy 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, alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.
