style="text-indent:25px">316L不銹鋼厚壁管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。316l不銹鋼厚壁管的較大碳含量0.03,可用于焊接后不能進行退火和需要較大耐腐蝕性的用途中。316l不銹鋼厚壁管耐腐蝕性，耐腐蝕性能優(yōu)于304不銹鋼，在漿和造紙的生產(chǎn)過程中具有良好的耐腐蝕的性能。而且316L不銹鋼還耐海洋和侵蝕性工業(yè)大氣的侵蝕。316l不銹鋼厚壁管耐熱性：在1600度以下的間斷使用和在1700度以下的連續(xù)使用中，316L不銹鋼具有好的耐氧化性能。在800-1575度的范圍內(nèi)，盡量不要連續(xù)作用316L不銹鋼，但在該溫度范圍以外連續(xù)使用316L不銹鋼時，該不銹鋼具有良好的耐熱性。316L不銹鋼厚壁管還耐海洋和侵蝕性工業(yè)大氣的侵蝕。貴州不銹鋼304價格</p><p
