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，還能提高該類鋼的抗氧化?？沽蚧涂谷邴}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。質(zhì)量控制是保證不銹鋼焊管質(zhì)量的必要途徑，而原料檢驗(yàn)則是不銹鋼焊管質(zhì)量控制中的首要，十分關(guān)鍵的一步。</p><div

不銹鋼焊管開裂是什么原因？不銹鋼焊管原料含有多種金屬元素，如：鉻、鎳、碳、鐵等。正是由于這些金屬元素的存在，才使得不銹鋼管具有良好的延展性和耐蝕性。不銹鋼焊管材具有伸長(zhǎng)率小、彈性大、硬化**高、從屈服到斷裂的塑性變形階段短等優(yōu)點(diǎn)，拉深變形后有時(shí)會(huì)出現(xiàn)拉深開裂，從凹模拉出時(shí)會(huì)立即發(fā)生開裂，深沖變形后有時(shí)會(huì)發(fā)生沖擊或振動(dòng)，深拉變形后會(huì)在貯存或使用一段時(shí)間后發(fā)生。那么，為什么不銹鋼焊管在拉深方面有缺點(diǎn)呢?開裂原因：奧氏體不銹鋼焊管的冷加工硬化**為0.34。奧氏體不銹鋼焊管是一種亞穩(wěn)定型，在變形過(guò)程中會(huì)發(fā)生相變并誘發(fā)馬氏體**，馬氏體**脆性大，易開裂，塑性變形過(guò)程中，隨著變形量的增加，誘發(fā)馬氏體**的含量越高，殘余應(yīng)力越大，加工過(guò)程中裂紋越容易發(fā)生。焊管不合格，造成焊縫減弱過(guò)多，使焊縫強(qiáng)度不夠。青海310s不銹鋼無(wú)縫焊管咨詢報(bào)價(jià)</p><p
