鉻的作用也是有益的，鉻除對(duì)奧氏體不銹鋼耐蝕性有重要影響外，還能提高該類(lèi)鋼的抗氧化。抗硫化和抗融鹽腐蝕等性能。鎳的影響1鎳對(duì)組織的影響鎳是強(qiáng)烈穩(wěn)定奧氏體且擴(kuò)大奧氏體相區(qū)的元素，為了獲得單一的奧氏體組織，當(dāng)鋼中含有低鎳含量約為8%。這便是18-8鉻鎳奧氏體不銹鋼的基本分，奧氏體不銹鋼中，隨著鎳含量的增加，殘余的鐵素體可完全消除，并降低σ相形成的傾向；同時(shí)馬氏體轉(zhuǎn)烴溫度降低，甚至可不出現(xiàn)λ→M相變，但是鎳含量的增加會(huì)降低碳在奧氏體不銹鋼中的溶解度，從而使碳化物析出傾向增強(qiáng)。2鎳對(duì)性能的影響鎳對(duì)奧氏體不銹鋼特別是對(duì)鉻鎳奧氏體不銹鋼力學(xué)性能的影響，主要是由鎳對(duì)奧氏體穩(wěn)定性的影響來(lái)決定，在鋼中可能發(fā)生馬氏體轉(zhuǎn)變的鎳含量范圍內(nèi)，隨著鎳含量的增加，鋼的強(qiáng)度降低而塑性提高，具有穩(wěn)定奧氏體組織的鉻鎳奧氏體不銹鋼韌性（包括極低溫韌性）非常優(yōu)良，因而可作為低溫鋼使用，這是眾所周知的，對(duì)于具有穩(wěn)定奧氏體組織的鉻錳奧氏體不銹鋼，鎳的加入可進(jìn)一步改善其韌性。鎳還可降低奧氏體不銹鋼的冷加工硬化傾向，這主要是由于奧氏體穩(wěn)定性增大，減少以至消除了冷加工過(guò)程中的馬氏體轉(zhuǎn)變，同時(shí)對(duì)奧氏體本身的冷加工硬化作用不太明顯。設(shè)備投入使用前必須把銹***掉,徹底清理過(guò)的表面應(yīng)通過(guò)鐵試驗(yàn)和/或水試驗(yàn)進(jìn)行檢驗(yàn)。</p><div
