耐腐蝕性:600合金對于各種腐蝕介質都具有耐腐蝕性。鉻的成分使該合金在氧化條件下比鎳99.2(合金200)和鎳99.2(合金201,低碳)具有更好的耐腐蝕性。
同時,較高的鎳含量是合金在還原條件和堿性溶液中具有很好法人耐腐蝕性,并且能夠有效的防治氯-鐵應力腐蝕開裂。
600合金在乙酸、醋酸、蟻酸、硬脂酸等有機酸中具有很好的耐腐蝕性,在無機酸中具有中等的耐蝕性。
在核反應堆中一次和二次循環使用的高純度水中具有很優秀的耐蝕性。600尤其突出的性能是能夠抵抗氯氣和氯化氫的腐蝕,應用溫度達650℃。
在高溫下,退火態和固溶處理態的合金在空氣中具有良好的抗氧化剝落性能和高強度。
該合金也能抵抗氨氣和滲氮、滲碳氣氛,但是在氧化還原條件交替變化時,合金會受到部分氧化介質的腐蝕(如綠色死亡液)。
1.has good resistance to reduction,oxidation,nitriding medium corrosion performance.
2.At room temperature and high temperature have good resistance to stress corrosion cracking performance.
3.have a good resistance to dry chlorine and hydrogen chlorine gas corrosion performance.
4.In the minus,at room temperature and high temperature have good mechanical properties.
5.Has a good creep rupture strength, recommended for use in more than 700 ℃ working environment.
Corrosion resistance: 600 alloy has corrosion resistance to various corrosive media. The composition of chromium makes this alloy have better corrosion resistance under oxidation conditions than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon).
At the same time, the higher nickel content is that the alloy has good corporate corrosion resistance in reducing conditions and alkaline solutions, and can effectively prevent chloride-iron stress corrosion cracking.
Alloy 600 has good corrosion resistance in acetic acid, acetic acid, formic acid, stearic acid and other organic acids, and medium corrosion resistance in inorganic acids.
High purity water used in nuclear reactors for one and two cycles has excellent corrosion resistance. 600 is particularly outstanding performance is able to resist the corrosion of chlorine and hydrogen chloride, the application temperature of 650 ℃.
At high temperature, the annealed and solution treated alloys have good resistance to oxidation spalling and high strength in air.
The alloy can also resist ammonia and nitriding and carburizing atmospheres, but when the redox conditions are changed alternately, the alloy will be corroded by some oxidizing media (such as green death fluid).
