不銹鋼板圓管1.4313是馬氏體級，耐銹蝕高朝，熱治療后耐久度性好。X3CrNiMo13-4鋼的機耐磨性是因為有機化學好分中鉬和鎳的高量。這個不銹鋼板添加圖片劑限制了加劇級碳量的要——給定酸度該是于奧氏體不銹鋼板圓管。即便是鎳量不夠，但鎳量約為4%，相關性加強了鋼對各樣銹蝕周圍環境的對抗力——多次機耐磨性。X3CrNiMo13-4鋼顧客可產生的超過300℃在高溫下的工作的元件和元件，并且暴漏在各樣銹蝕周圍環境中的元件，的同時增加已經可以的的表面要求括抗氯化物物理性質)。QT650.QT780和QT900要求下，熱治療后常用支付鋼材。半制成品用來是由產生的.化學工業.在冶金業和電力能源業，泄壓閥機暴漏在高濕潤環境溫度下.泵.收縮機主件。鋼不合焊接加工。
