304裝飾管1.4313是馬氏體級，耐腐燭高，熱正確辦理后耐用性好。X3CrNiMo13-4鋼的設備耐金屬腐蝕不銹鋼性是基于耐金屬腐蝕不銹鋼成份中鉬和鎳的高含碳量。以上鎳鋼增長劑束縛了新增級碳含碳量的是需要——給定氧化還原電位等于于奧氏體304裝飾管。既然鎳含碳量較低，但鎳含碳量約為4%，同質性的提升了鋼對各種各樣的各樣的腐燭場景的抗拒力——二級設備耐金屬腐蝕不銹鋼性。X3CrNiMo13-4鋼訪客可分娩萬代高達300℃在溫度因素下的工作的工件和工件，以其泄露在各種各樣的各樣的腐燭場景中的工件，另外提高夠了的面先決的條件括抗氯化物特性)。QT650.QT780和QT900先決的條件下，熱正確辦理后常用交工矩形鋼。半生育設備應用在油氣分娩.石油化工.在冶金機械和能源技術企業，鍋輪機泄露在高一個溫和溫度低下.泵.壓縮的機組件。鋼隱疼合焊接加工。
