鋁碳素鋼1.4313是馬氏體級，耐耐氧化性強性好，熱治理后持久性好。X3CrNiMo13-4鋼的機戒特點是根據生物學好分中鉬和鎳的高成分。這碳素鋼獲取劑受到限制了增高級碳成分的需求——給定濃硫酸濃度相同于奧氏體鋁碳素鋼。固然鎳成分不夠，但鎳成分約為4%，相關性提高了了鋼對不同的耐氧化性強壞境的抵觸力——分批機戒特點。X3CrNiMo13-4鋼普通用戶可研發可以達到300℃在溫度因素下業務的元件和元件，或展現在不同的耐氧化性強壞境中的元件，一同保持著夠的的表面情況括抗氯化物經營性質)。QT650.QT780和QT900情況下，熱治理后最應交貨方鋼管。半的成品使用于頁巖油研發.化工制造業.在冶金工程和能量制造業，泄壓閥機展現在高和緩環境溫度下.泵.文件冰箱壓縮機元件。鋼不適反應合對接焊。
