style="text-indent:25px">由21%鉻，2.5%鉬及4.5%鎳氮合金構(gòu)成的復(fù)式不銹鋼，它的屈從強度是奧氏體不銹鋼的兩倍，這一特性使設(shè)計者在設(shè)計產(chǎn)品時減輕重量，讓這種合金比316，317L更具有優(yōu)勢。由于該鋼鉻和鉬的含量都很高，因而具有極好的抗點腐蝕和平均腐蝕的才能。雙相組織保證了該鋼具有很高的抗應(yīng)力腐蝕決裂的才能，同機遇械強度也很高。316L不銹鋼管的性能和適用范圍316L不銹鋼管管材，具有優(yōu)越的力學(xué)性能和耐蝕性能，以及良好的焊接性。在石油及自然氣工業(yè)、海洋工程、化學(xué)工業(yè)等行業(yè)具有普遍的用處。</p><p style="text-indent:25px">304不銹鋼焊管工程安裝中的注意事項：碳在不銹鋼焊管中的兩重性碳是工業(yè)用鋼的主要元素之一，鋼的性能與組織在很大程度上決定于碳在鋼中的含量及其分布的形式，在不銹鋼中碳的影響尤為明顯。碳在不銹鋼中對組織的影響主要表現(xiàn)在兩方面，一方面碳是穩(wěn)定奧氏體的元素，并且作用的程度很大（約為鎳的30倍），另一方面由于碳和鉻的親和力很大，與鉻形成—系列復(fù)雜的碳化物。所以，從強度與耐腐燭性能兩方面來看，碳在不銹鋼中的作用是互相矛盾的。不銹鋼管在**工業(yè)、科學(xué)技術(shù)和經(jīng)濟建設(shè)中的地位愈加重要。</p><div
