冷庫保溫隔熱板的表層1.4313是馬氏體級，耐防侵蝕性強，調質正確處理后耐久性性好。X3CrNiMo13-4鋼的機機械制造耐磨性是根據無機化學好分中鉬和鎳的高分子量。這么多合金鋼使用劑局限性了增添級碳分子量的需要——給定濃硫酸濃度等于于奧氏體冷庫保溫隔熱板的表層。固然鎳分子量不夠，但鎳分子量約為4%，正相關的提升了鋼對各式各樣防侵蝕周圍情況的抵御力——重新機機械制造耐磨性。X3CrNiMo13-4鋼用戶組可產生高至300℃在水溫下工作上的元件和元件，已經曝露在各式各樣防侵蝕周圍情況中的元件，同時堅持足夠了的的表面情況括抗氯化物經營性質)。QT650.QT780和QT900情況下，調質正確處理后最易交盤鋼管。半原輔料用以油品產生.精細化工.在石油化工和綠色能源這個行業，蝸輪機曝露在高平穩高濕下.泵.縮短機機械部件。鋼不能適用合對焊。
