316和317不銹鋼（317不銹鋼的性能見后）是含鉬不銹鋼種。317不銹鋼中的鉬含量略高明于316不銹鋼.由于鋼中鉬，該鋼種總的性能優(yōu)于310和304不銹鋼，高溫條件下，當(dāng)***的濃度低于15%和高于85%時，316不銹鋼具有***的用途。316不銹鋼還具有良好的而氯化物侵蝕的性能，所以通常用于海洋環(huán)境。 </p> <p> <br /> </p> <p>

鉻的作用也是有益的，鉻除對奧氏體不銹鋼耐蝕性有重要影響外，還能提高該類鋼的抗氧化?？沽蚧涂谷邴}腐蝕等性能。鎳的影響1鎳對組織的影響鎳是強(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鎳對性能的影響鎳對奧氏體不銹鋼特別是對鉻鎳奧氏體不銹鋼力學(xué)性能的影響，主要是由鎳對奧氏體穩(wěn)定性的影響來決定，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程中的馬氏體轉(zhuǎn)變，同時對奧氏體本身的冷加工硬化作用不太明顯。不銹鋼焊管原料和半成品在周轉(zhuǎn)和運(yùn)輸過程中，應(yīng)配備必要的防鐵離子污染和磕傷、劃傷的運(yùn)輸工裝。</p><div
