不銹鋼1.4313是馬氏體級，耐銹蝕高，熱操作后耐久度性好。X3CrNiMo13-4鋼的機戒機器耐被腐蝕性是仍然生物不銹鋼成分中鉬和鎳的高量。某些合金類加上劑限止了增高級碳量的需要——給定溶液濃度一樣于奧氏體不銹鋼。雖然說鎳量較低，但鎳量約為4%，為顯著不斷提高了鋼對不同銹蝕氛圍的對抗力——兩次機戒機器耐被腐蝕性。X3CrNiMo13-4鋼大家可生育高達模型300℃在的溫度下操作的元器件和元器件，各類被外露在不同銹蝕氛圍中的元器件，一起保證充裕的表明標準括抗氯化物性)。QT650.QT780和QT900標準下，熱操作后通常交貨H型鋼。半樣品應用在原油生育.煤化工.在冶金工程和能源開發業，渦輪增壓機被外露在高一個溫和溫度下.泵.降低機構件。鋼惡化的情況合焊接生產。
