    材料特性 Material Characteristics

    Monel400是一種用量最大、用途最廣、綜合性能極佳的耐腐蝕合金。此合金在氫氟酸和氟氣介質中具有優異的耐蝕性,對熱濃堿液也有優良的耐蝕性。

    Monel400的金相結構:Monel400合金的組織為高強度的單相固溶體。

    Monel400的耐腐蝕性:Monel400合金在氟氣、鹽酸、硫酸、氫氟酸以及它們的派生物中有極優秀的耐蝕性。同時在海水中比銅基合金更具耐蝕性。

    酸介質:Monel400合金在濃度小于85%的硫酸中都是耐蝕的。Monel400是可耐氫氟酸中為數極少的重要材料之一。

    水腐蝕:Monel400合金在多數水腐蝕的情況下,不僅耐蝕性極佳,而且孔蝕、應力腐蝕等也很少發現,腐蝕速度小于0.025mm/a。

    高溫腐蝕:Monel400在空氣中連續工作的最高溫度一般在600℃左右,在高溫蒸汽中,腐蝕速度小于0.026mm/a。

    氨:由于Monel400合金鎳含量高,故可耐585℃以下無水氨和氨化條件下的腐蝕。

    Monel400 is one of the largest amount,the most widely used,the overall performance of excellent corrosion resistance alloy,the alloy in hydrofluoric acid and fluorine gas medium has excellent corrosion resistance,the hot concentrated alkali also has excellent corrosion resistance.while also is resistant to neutral solusion,water seawater,air,organic compounds such as corrosion,another inportant feature is generally not produce stress corrosion cracking,so its cutting performance is good.

    Metallographic structure: high-strength single-phase solid solution.

    Corrosion resistance: Monel400 alloy in fluorine, hydrochloric acid, hydrofluoric acid and their derivatives have very good corrosion resistance. While in seawater it is more corrosion resistant than copper-based alloys.

    Acid medium: Monel400 alloy is corrosion resistant in sulfuric acid with a concentration of less than 85%. it is one of the very few important materials.

    Water corrosion: In most cases of water corrosion, Monel400 alloy not only has excellent corrosion resistance, but also rarely finds pitting corrosion and stress corrosion. The corrosion rate is less than 0.025mm/a.

    High temperature corrosion: The maximum temperature for continuous operation of Monel400 in air is generally around 600 . In high temperature steam, the corrosion rate is less than 0.026mm/a.

    Ammonia: Because the higesth nickel content Monel400 alloy, it is resistant to corrosion under anhydrous ammonia and ammoniated conditions below 585 .
