We are a leading manufacturer of alloy pipe and pipe fittings, we have more than 15year experience in producing Monel 400 pipe and pipe fittings such as Monel 400 Elbow, Monel 400 Reducer, Monel 400 Tee, and Monel 400 Stub end.
Introduction
Monel 400 is a kind of corrosion resistant alloy with the largest dosage, the most extensive use and the best comprehensive performance.This alloy has excellent corrosion resistance in hydrofluoric acid and fluorine gas medium and good corrosion resistance to hot concentrated alkali liquor.It is also resistant to corrosion of neutral solutions, water, sea water, atmosphere and organic compounds.One of the important characteristics of the alloy is that it generally does not produce stress corrosion cracks and has good
cutting performance.

Corrosion resistance
Acid medium: Monel400 is corrosion resistant in sulfuric acid with a concentration of less than 85%. Monel400 is one of the few important materials in hydrofluoric acid resistance. Water corrosion: Monel400 alloy not only has excellent corrosion resistance in most cases of water corrosion, but also is seldom found with hole corrosion, stress corrosion, etc. The corrosion rate is less than 0.025mm/a. High temperature corrosion: Monel400 continuous work in air generally at about 600 ℃, the highest temperature in the high temperature steam, corrosion rate is less than 0.026 mm/a.Ammonia: because Monel400 high nickel alloy content, reason can be below 585 ℃ anhydrous ammonia and ammoniation under the condition of corrosion.
