201，低碳）具有更好的耐腐蝕性。同時(shí)，較高的鎳含量使合金在還原條件和鹼性溶液中具有很好的耐腐蝕性，並且能有效地防止氯-鐵應(yīng)力腐蝕開(kāi)裂。2.4816合金在乙酸、醋酸、蟻酸、硬脂酸等有機(jī)酸中具有很好的耐蝕性，在無(wú)機(jī)酸中具有中等的耐蝕性。在核反應(yīng)堆中一次和二次循環(huán)使用的高純度水中具有很優(yōu)秀的耐蝕性。600尤其突出的性能是能夠抵抗幹氯氣和氯化氫的腐蝕，應(yīng)用溫度達(dá) 650℃。在高溫下，退火態(tài)和固溶處理態(tài)的合金在空氣中具有很好的抗氧化剝落性能和高強(qiáng)度。該合金也能抵抗氨氣和滲氮、滲碳?xì)夥?，但是在氧化還原條件交替變化時(shí)，合金會(huì)受到部分氧化介質(zhì)的腐蝕（如綠色死亡液）特性： 1.具有很好的耐還原、氧化、氮化介質(zhì)腐蝕的性能 2.在室溫及高溫時(shí)都具有很好的耐應(yīng)力腐蝕開(kāi)裂性能 3.具有很好的耐幹燥氯氣和氯化氫氣體腐蝕的性能 4.在零下、室溫及高溫時(shí)都具有很好的機(jī)械性能 5.具有很好的抗蠕變斷裂強(qiáng)度，推薦用在700℃以上的工作環(huán)境。
