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**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，monel400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**，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**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 mainoperating environment:

monel400 corrosion resistance isgenerally better than nickel copper, it is more resistant to thecorrosion of reductive medium than pure nickel, corrosionresistance to sulfuric acid, phosphoric acid, carbon is very good.especially the corrosion resistance of hydrochloric acid also hasexcellent corrosion resistance to thermal concentrated alkali.monel400 alloys have excellent corrosion resistance in fluorine,hydrochloric acid, sulfuric acid, hydrofluoric acid and theirderivatives. at the same time, it is more corrosion resistant thancopper based alloy in seawater.

monel400 is a deformablenickel-copper nickel-based alloy with good resistance to seawatercorrosion and chemical corrosion, and strong resistance to chloridestress corrosion cracking. the alloy is one of the few alloys thatcan be used in fluoride. it has good resistance to oxide stressfission corrosion in hydrofluoric acid and fluorine medium, such asseawater and brine environment.

monel 400 also have very goodcorrosion resistance in medium concentrations of alkaline and saltsolutions.

in cold alkaline environment, thealloy is used in weak acid such as sulfur, hydrogen fluorideenvironment.

acid medium: monel400 are corrosionresistant in sulfuric acid with concentration less than 85%.monel400 is one of the few important materials for hydrofluoricacid resistance.

water corrosion: monel400 alloys inmost water corrosion conditions, not only excellent corrosionresistance, but also pore corrosion, stress corrosion and porecorrosion, stress corrosion and so on. the corrosion rate is lessthan mm/a.0.025

high temperature corrosion: themaximum temperature for continuous operation of monel400 in air isgenerally about 600℃. in high temperature steam, the corrosion rateis less than mm/a.0.026 ammonia: due to the high nickel content ofmonel400 alloy, it can resist corrosion under the condition ofanhydrous ammonia and ammoniation below 585℃.

supporting welding materials andwelding process: the welding of monel400 alloy is recommended toadopt aws a5.14 wire ernicu-7 or aws a5.11 electrode. the size ofwelding material is: american smc and german nickel, weldingprocess and instruction are welcome to call for.
