304不繡鋼1.4313是馬氏體級，耐灼傷高朝，熱上班后耐久性性好。X3CrNiMo13-4鋼的機制性能方面方面是鑒于有機化學好分中鉬和鎳的高的濃度的。這么多合金屬修改劑制約了新增級碳的濃度的的須得——給定氧濃度能裝于奧氏體304不繡鋼。即使鎳的濃度的不太高，但鎳的濃度的約為4%，顯著性從而提高了鋼對各項各樣的灼傷氛圍的抵御力——2次機制性能方面方面。X3CrNiMo13-4鋼消費者可分娩萬代高達300℃在溫度下上班的配件上的和配件上的，時顯示在各項各樣的灼傷氛圍中的配件上的，時堅持足以的的表面環境括抗氯化物規定性)。QT650.QT780和QT900環境下，熱上班后通常交樓矩形鋼。半的成品用來原油使用量分娩.化學工業.在礦冶和發熱能源領域，齒輪機顯示在高和緩高濕下.泵.壓縮視頻機組件。鋼不是合熔接。
