Monel400 / N04400 / DIN2.4360

Monel 400 is a nickel-copper alloy (about 67% Ni-23% Cu) with high strength and excellent corrosion resistance. It has wide-range such as sea water, high temperatures, salt and caustic solutions.
As Monel 400 has many good performance as following: excellent combination property, resistant Resistant to seawater and steam at high temperatures, Excellent resistance to rapidly flowing brackish water or seawater, Excellent resistance to stress corrosion cracking in most freshwaters, Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerate, Offers some resistance to hydrochloric and sulfuric acids at modest temperatures and concentrations, but is seldom the material of choice for these acids, Excellent resistance to neutral and alkaline sale, Resistance to chloride induced stress corrosion cracking, Good mechanical properties from sub-zero temperatures up to 1020° F, High resistance to alkalis, it is widely used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners and heat exchangers.


Monel K500 / N05500

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the Monel 400 with greater strength and hardness. It also has low permeability and nonmagnetic to temperatures as low as -101 Deg, always used for pump shafts, oil-well tools and instruments, doctor blades and scrapes, springs, valve rim, fasteners, and marine propeller shafts.
Monel K500 has Corrosion resistance in an extensive range of marine and chemical environments. From pure water to non-oxidizing mineral acids, salts and alkalis. Excellent resistance to high velocity sea water, Resistant to a sour-gas environment, Excellent mechanical properties from sub-zero temperatures up to about 480C, Non-magnetic and good hardnedd.
