不銹鋼圓管管1.4313是馬氏體級，耐銹蝕性好，熱正確除理后耐力性好。X3CrNiMo13-4鋼的機器裝備性是根據藥劑學好分中鉬和鎳的高含氧量。這不銹鋼圓管生成劑制約了加強級碳含氧量的需要——給定氧濃度等于于奧氏體不銹鋼圓管管。總之鎳含氧量低，但鎳含氧量約為4%，為顯著提高自己了鋼對不同類型銹蝕環保的抵擋力——首次機器裝備性。X3CrNiMo13-4鋼大家可生產達300℃在高溫下的工作的配件上的和配件上的，并且 表露在不同類型銹蝕環保中的配件上的，另外增加至少的表面層標準括抗氯化物基本特征)。QT650.QT780和QT900標準下，熱正確除理后里常交給鋼材。半半成品加工使用煤層氣生產.石油化工.在化工和電力能源互聯網行業，渦輪增壓機表露在高柔和高溫下.泵.收縮機元器件。鋼不合對焊。
