耐腐蚀性及主要使用环境:
Monel400的耐腐蚀性能一般情况下比镍铜更优越,它比纯镍更耐还原性介质的腐蚀，比纯铜耐氧化性介质的腐蚀，对硫酸、磷酸、碳的耐腐蚀性非常好。特别是耐氢氯酸的腐蚀，对热浓碱也有优良的耐腐蚀性。Monel400合金在氟气、盐酸、硫酸、氢氟酸以及它们的派生物中有极优秀的耐蚀性。同时在海水中比铜基合金更具耐蚀性。
Monel400属可变形加工的镍-铜系镍基合金，具有很好的耐海水腐蚀和抗化学腐蚀性能，耐氯化物应力腐蚀开裂性能强。该合金是为数不多的能使用在氟化物中的合金之一。在氢氟酸和氟气介质中具有很好的耐氧化物应力裂变腐蚀，如海水、盐水环境中。
在中等浓度的碱性和盐溶液中，Monel 400也有非常好的抗腐蚀性能。
在较冷的的碱性环境下，该合金被用在弱酸如硫磺、氟化氢环境中。
酸介质:Monel400在浓度小于85%的硫酸中都是耐蚀的。Monel400是可耐氢氟酸中为数极少的重要材料之一。
水腐蚀:Monel400合金在多数水腐蚀情况下，不仅耐蚀性极佳，而且孔蚀、应力腐蚀等也很少发现，腐蚀速度小于0.025mm/a。
高温腐蚀:Monel400在空气中连续工作的最高温度一般在600℃左右，在高温蒸汽中，腐蚀速度小于0.026mm/a。氨:由于Monel400合金镍含量高，故可耐585℃以下无水氨和氨化条件下的腐蚀。

Corrosion resistance and main operating environment:
Monel400 corrosion resistance is generally better than nickel copper, it is more resistant to the corrosion of reductive medium than pure nickel, corrosion resistance to sulfuric acid, phosphoric acid, carbon is very good. Especially the corrosion resistance of hydrochloric acid also has excellent corrosion resistance to thermal concentrated alkali. Monel400 alloys have excellent corrosion resistance in fluorine, hydrochloric acid, sulfuric acid, hydrofluoric acid and their derivatives. At the same time, it is more corrosion resistant than copper based alloy in seawater.
Monel400 is a deformable nickel-copper nickel-based alloy with good resistance to seawater corrosion and chemical corrosion, and strong resistance to chloride stress corrosion cracking. The alloy is one of the few alloys that can be used in fluoride. It has good resistance to oxide stress fission corrosion in hydrofluoric acid and fluorine medium, such as seawater and brine environment.
Monel 400 also have very good corrosion resistance in medium concentrations of alkaline and salt solutions.
In cold alkaline environment, the alloy is used in weak acid such as sulfur, hydrogen fluoride environment.
Acid medium: Monel400 are corrosion resistant in sulfuric acid with concentration less than 85%. Monel400 is one of the few important materials for hydrofluoric acid resistance.
Water corrosion: Monel400 alloys in most water corrosion conditions, not only excellent corrosion resistance, but also pore corrosion, stress corrosion and pore corrosion, stress corrosion and so on. The corrosion rate is less than mm/a.0.025
High temperature corrosion: the maximum temperature for continuous operation of Monel400 in air is generally about 600℃. In high temperature steam, the corrosion rate is less than mm/a.0.026 Ammonia: due to the high nickel content of Monel400 alloy, it can resist corrosion under the condition of anhydrous ammonia and ammoniation below 585℃.
