1.4313是馬氏體級，耐腐蝕性高，熱處理后耐久性好。X3CrNiMo13-4鋼的機械性能是由于化學成分中鉬和鎳的高含量。這些合金添加劑限制了增加a級碳含量的需要——給定濃度相當于奧氏體不銹鋼。雖然鎳含量不高，但鎳含量約為4%，顯著提高了鋼對各種腐蝕環(huán)境的抵抗力——二次機械性能。X3CrNiMo13-4鋼用戶可生產(chǎn)高達300℃在溫度下工作的零件和零件，以及暴露在各種腐蝕環(huán)境中的零件，同時保持足夠的表面條件括抗氯化物性質(zhì))。QT650.QT780和QT900條件下。半成品用于石油生產(chǎn).化工.在冶金和能源行業(yè)，渦輪機暴露在高溫和低溫下.泵.壓縮機部件。鋼不適合焊接。
