蒙乃尔 400 镍基合金无缝管

ASTM B 163 / B730 / ASTM B165 / B725 Nickel Alloy Pipe 蒙乃尔 400 / 英文 2.4360 / Monel K500 / 2.4375

Monel 400®, Nickelvac® 400, Nicorros® 400 蒙乃尔 400 is a combination of nickel and copper and is hardened by cold working only. This alloy is widely renowned for for its corrosion resistant properties against flowing sea – water and is extensively used for marine applications. Monel is also extremely resistant to stress corrosion cracking in most freshwaters. High temperature ( 为止 1000 °华氏度) has no effect on this alloy and it also has excellent mechanical properties at subzero temperatures.

3.机械性能

strength of extension:σb≥450Mpa

屈服强度:σb≥170Mpa

延性:δ≥30%

4.耐腐蚀性

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, 等. The corrosion rate is less than 0.025mm/a.

High temperature corrosion: Monel400 continuous work in air generally at about 600 °C, 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.
