304304不繡鋼1.4313是馬氏體級，耐金屬腐化性強，熱加工除理后耐力性好。X3CrNiMo13-4鋼的機戒效能是根據電化學精分中鉬和鎳的高濃度值。此類合金鋼含有劑控制了新增級碳濃度值的須要——給定濃度值很多于奧氏體304304不繡鋼。即使鎳濃度值不太高，但鎳濃度值約為4%，有明顯從而提高了鋼對不同金屬腐化生態場景的抵擋力——2次機戒效能。X3CrNiMo13-4鋼微信用戶可種植敢達300℃在場景溫度下上班的元器件和元器件，并且暴曬在不同金屬腐化生態場景中的元器件，時候保持良好夠的表面層先決水平括抗氯化物性)。QT650.QT780和QT900先決水平下，熱加工除理后最喜歡交房鋼材。半現做用做頁巖油種植.化工產業.在冶金工程和能源資源產業，鍋輪機暴曬在高一個溫和地溫下.泵.收縮機控制部件。鋼難受合對焊。
