不銹鋼304圓管1.4313是馬氏體級，耐銹蝕高，熱凈化除理后耐用度性好。X3CrNiMo13-4鋼的機戒設備性參數是原因化學上組成成分中鉬和鎳的高含碳量。這樣的鎂合金加上劑影響了曾加級碳含碳量的必須要——給定氧化還原電位差不多于奧氏體不銹鋼304圓管。即便是鎳含碳量不太高，但鎳含碳量約為4%，明顯提高自己了鋼對不同各樣的銹蝕壞境的抗擊力——兩次機戒設備性參數。X3CrNiMo13-4鋼用戶的可分娩制造更是高達300℃在溫度下辦公的零機件和零機件，已經外露在不同各樣的銹蝕壞境中的零機件，時候堅持足夠的的表明環境括抗氯化物的性質)。QT650.QT780和QT900環境下，熱凈化除理后最易托付矩形鋼。半半成品加工適用石油天然氣分娩制造.精細化工.在有色金屬冶煉和清潔能源制造行業，齒輪機外露在高清新常溫下.泵.收縮機機件。鋼不適應合不銹鋼焊接。
