Pipe Monel 400 Nickel copper Alloy ASTM B163 seamless pipe

Chemical Element:
Ni 63.0min, Cu 28min~34max, Fe2.5max, Mn 2.0max, C 0.3max, Si 0.5max, S 0.024max
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.

Metallurgical structure
Monel 400 alloy is high-intensity single-phase solid solution.

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 degree in general in the air, in the high temperature steam, the corrosion rate less than 0.026mm / a. Amm
