此外，鎳還提高奧氏體不銹鋼的高溫抗氧化性能，這主要與鎳改善了鉻的氧化膜的成分。結(jié)構(gòu)和性能降低，并且鎳含量越高越有害，這主要是由于鋼中晶界處低熔點(diǎn)硫化鎳所致，一般來(lái)說(shuō)，簡(jiǎn)單的鉻鎳（及鉻錳氮）奧氏體不銹鋼*用于要求不銹性和耐氧化性介質(zhì)。比如硝酸等）的使用條件下，鉬作為奧氏體不銹鋼中的重要合金元素加入到鋼中使其使用范圍進(jìn)一步擴(kuò)大，鉬的作用主要是提高鋼在還原性介質(zhì)鉬的影響1鉬對(duì)組織的影響鉬和鉻都是形成和穩(wěn)定鐵素體并擴(kuò)大鐵素體相區(qū)的元素，鉬形成鐵素體的能力與鉻相當(dāng)。鉬還促進(jìn)奧氏體不銹鋼中金屬間相，比如σ相，κ相，和Laves相等的沉淀，對(duì)鋼的耐蝕性和力學(xué)性能都會(huì)產(chǎn)生不利影響，特別是導(dǎo)致塑性，韌性下降。為使奧氏體不銹鋼保持單一的奧氏體組織，隨著鋼中鉬含量的增加，奧氏體形成元素（鎳，氮及錳等）的含量也要相應(yīng)提高，以保持鋼中鐵素體與奧氏體形成元素之間的平衡。2鉬對(duì)性能的影響鉬對(duì)奧氏體不銹鋼的氧化作用不，因此當(dāng)鉻鎳奧氏體不銹鋼保持單一的奧氏體組織且無(wú)金屬間析出時(shí)，鉬的加入對(duì)其室溫力學(xué)性能影響不大，但是，隨著鉬含量的增加，鋼的高溫強(qiáng)度提高，比如持久，蠕變等性能均獲較大改善，因此含鉬不銹鋼也常在高溫下應(yīng)用。福建430不銹鋼無(wú)縫焊管加工定制必須經(jīng)常對(duì)裝飾不銹鋼焊管表面進(jìn)行清潔擦洗，去除附著物，消除引發(fā)修飾的外界因素.</p><div

1.使用環(huán)境中存在氯離子。 </p> <p> <br /> </p> <p> 氯離子***存在，比如食鹽、汗跡、海水、海風(fēng)、土壤等等。不銹鋼在氯離子存在下的環(huán)境中，腐蝕很快，甚至超過(guò)普通的低碳鋼。 </p> <p> <br /> </p> <p> 所以對(duì)不銹鋼的使用環(huán)境有要求，而且需要經(jīng)常擦拭，除去灰塵，保持清潔干燥。 </p> <p> <br /> </p> <p> 316和317不銹鋼（317不銹鋼的性能見(jiàn)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(shí)，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 />
