Product Description
Monel 400 Alloy Steel Pipe and Tube UNS N04400 EN 2.4360 2.4361

Monel 400 is a nickel-copper alloy resistant to sea water and steam at high temperatures as well as to salt and caustic solutions. It is a solid solution alloy that can only be hardened by cold working. Has good corrosion resistance, good weldability and high strength. Has low corrosion rate in rapidly flowing brackish or seawater, excellent resistance to stress-corrosion cracking in most freshwaters, and resistant to a variety of corrosive conditions. Widely used in marine applications and other non-oxidizing chloride solutions. Particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. It has great mechanical properties at subzero temperatures, can be used in temperatures up to 1000° F, and its melting point is 2370-2460° F.

Characteristic as below:
Monel 400 is an extremely combination property that use for largest amount and most widely corrosion resistance alloy. This alloy in the hydrofluoric acid and fluoride gas medium with excellent corrosion resistance, as well as to the hot concentrated alkali. At the same time, is also corrosion resistant to neutral solution, sea water, air, organic compounds. An important feature of this is generally do not generate a stress corrosion cracking, good cutting performance.
Monel 400 Metallurgical structure:
Monel 400 alloy is high-intensity single-phase solid solution.

Monel 400 Corrosion resistance:
Monel 400 alloy in the fluoride gas, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives have a very good corrosion resistance property, and possess better corrosion resistance more than the copper alloy in the sea water. Acid medium: Monel 400 have corrosion resistance in less than 85% consistency of sulfuric acid. Monel 400 is an important material that resistant to hydrofluoric acid. Water corrosion: Monel 400 alloy in most corrosion cases of water, not only excellent corrosion resistance, but also less pitting, stress corrosion, the corrosion rate less than 0.025mm / a. High temperature corrosion: Monel 400 for the work of the highest temperature at about 600 °C in general in the air, in the high temperature steam, the corrosion rate less than 0.026mm / a. Ammonia: Monel 400 can be resistant to an hydrous ammonia and aminate conditions corrosion below 585 °C due to the high nickel.
Monel 400 alloy is a multi-purpose material in many industrial applications: 
1. Seamless water pipe in the power factory
2. Sea-water exchanger and evaporator 
3. Sulfuric acid and hydrochloric acid environment 
4. Crude distillation 
5. Sea-water in the use of equipment and propeller shaft 
7. Manufacturing hydrochloric acid equipment used in the production of pump and valve
