奧氏體不銹鋼中可出現(xiàn)鐵素體（δ）組織，研究表明，在鉻鎳奧氏體不銹鋼中，當(dāng)碳含量為，鉻含量為18%時(shí)。為獲得穩(wěn)定的單一奧氏體組織，所需鎳含量低，約為8%，就這一點(diǎn)而言，常用的18Cr—8Ni型鉻鎳奧氏體不銹鋼是含鉻，鎳量配比為適宜的一種。有奧氏體不銹鋼中，隨著鉻含量的增加，廣西430不銹鋼無縫焊管供應(yīng)。一些金屬間相（比如δ相）的形成傾向增大，當(dāng)鋼中含有鉬時(shí)，鉻含含量會(huì)增加還會(huì)χ相等的形成，如前所述，σ，χ相的析出不*降低鋼的塑性和韌性，而且在一些條件下還降低鋼的耐蝕性，奧氏體不銹鋼中鉻含量的提高可使馬氏體轉(zhuǎn)烴溫度（Ms）下降，從而提高奧氏體基體的穩(wěn)定性。因此高鉻（比如超過20%）奧氏體不銹鋼即使經(jīng)過冷加工和低溫處理也很難獲得馬氏體組織。鉻是強(qiáng)碳化物形成元素，在奧氏體不銹鋼中也不例外，廣西430不銹鋼無縫焊管供應(yīng)，奧氏體不銹鋼中常見的鉻碳化物有Cr23C6；當(dāng)鋼中含有鉬或鉻時(shí)，還可見到期Cr6C等碳化物，它們的形成在某些條件下對鋼的性能會(huì)產(chǎn)生重要影響?！?鉻對性能的影響：一般來說，廣西430不銹鋼無縫焊管供應(yīng)，只要奧氏體不銹鋼保持完全奧氏體組織而沒有δ鐵素體等的形成，*提高鋼中鉻含量不會(huì)對力學(xué)性能有影響，鉻對奧氏體不銹鋼性能影響大的是耐蝕性，主要表現(xiàn)為：鉻提高鋼的耐氧化性介質(zhì)和酸性氯化物介質(zhì)的性能。設(shè)備投入使用前必須把銹***掉,徹底清理過的表面應(yīng)通過鐵試驗(yàn)和/或水試驗(yàn)進(jìn)行檢驗(yàn)。廣西430不銹鋼無縫焊管供應(yīng)</p><div

奧氏體型不銹鋼同絕大多數(shù)的其它金屬材料相似，其抗拉強(qiáng)度、屈服強(qiáng)度和硬度，隨著溫度的降低而提高；塑性則隨著溫度降低而減小。其抗拉強(qiáng)度在溫度15~80°C范圍內(nèi)增長是較為均勻的。更重要的是：隨著溫度的降低，其沖擊韌度減少緩慢，并不存在脆性轉(zhuǎn)變溫度。所以不銹鋼在低溫時(shí)能保持足夠的塑性和韌性。不銹鋼的耐熱性能是指高溫下，既有抗氧化或耐氣體介質(zhì)腐蝕的性能即熱穩(wěn)定性。鉻的影響鉻是奧氏體不銹鋼中主要的合金元素，奧氏體不銹鋼的不銹性和耐蝕性的獲得主要是由于在會(huì)質(zhì)作用下，鉻促進(jìn)了鋼的鈍化并使鋼保持穩(wěn)定鈍態(tài)的結(jié)果?！?鉻對組織的影響：在奧氏體不銹鋼中，鉻是強(qiáng)烈形成并穩(wěn)定鐵體的元素，縮小奧氏體區(qū)，隨著鋼中含量增加。廣西430不銹鋼無縫焊管供應(yīng)幾種焊接方法各具特點(diǎn)，目前使用**多的是氬弧焊和高頻焊。</p><div
