This alloy is most commonly used in a range of environments from mildly oxidizing to neutral and moderately reducing conditions. Other areas of application for this material are marine environments and other non-oxidizing chloride solutions.
It has excellent solderability and can withstand very high pressure and weight. The alloy has excellent mechanical properties at sub-zero temperatures, with a melting point of 2370¡ã – 2460¡ã F, and the product can be used at temperatures up to 1000¡ã C.
If hardened Monel 400 is the goal, cold working with a soft tooling material is the only option. By cold working, mechanical stress is used instead of heat to change the shape of the metal.
Alloy 400 is a nickel copper solid solution strengthened alloy. The alloy is characterized by moderate strength, good weldability, good general corrosion resistance and good toughness.
It is suitable for temperatures up to 1000¡ãF (538¡ãC). Alloy 400 has excellent resistance to cavitation and erosion in fast-flowing brackish or seawater.
Alloy 400 also has excellent corrosion resistance in a variety of media including seawater, hydrofluoric acid, sulfuric acid and alkalis. Used in marine engineering, chemical, hydrocarbon processing equipment and heat exchangers.
Alloy 400 is virtually immune to chloride stress corrosion cracking in typical environments. Generally, its corrosion resistance is good in reducing environment, but poor in oxidizing environment.
Alloys like Monel 400 flanges perform well in marine environments due to their chemical composition. The copper content is between 28% and 34% and is known as a superalloy due to its good corrosion resistance.
When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.
The strength of this nickel steel alloy is maintained to 1200¡ã F but stays ductile and tough down to temperatures of 400¡ã F. Its melting range is 2400-2460¡ã F.
Alloy K500 is refined by Electro Slag Refining (ESR), ensuring the cleanest and highest quality of material is supplied.
Monel 400 is a nickel-copper alloy (about 67% Ni ¨C 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.
Alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.
MONEL K500 is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.
Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness.
Monel 400 products on a project basis is one of our strongest capabilities and is unmatched in our industry.
