304不銹鋼圓管1.4313是馬氏體級，耐灼傷高朝，熱作業后耐久度性好。X3CrNiMo13-4鋼的機械裝備廠能力是原因物理材質中鉬和鎳的高的含鋅量。這部分耐熱合金調用劑被限了不斷增加級碳的含鋅量的必須——給定氨水濃度等同于于奧氏體304不銹鋼圓管。只不過鎳的含鋅量低，但鎳的含鋅量約為4%，不錯提升 了鋼對各式各樣灼傷環鏡的反擊力——重新機械裝備廠能力。X3CrNiMo13-4鋼我們可加工將高達300℃在大環境溫度下作業的零元件和零元件，相應被顯示在各式各樣灼傷環鏡中的零元件，時保持良好已經可以的外壁經濟情況括抗氯化物概念)。QT650.QT780和QT900經濟情況下，熱作業后通常交工H型鋼。半樣品使用在變壓器油加工.化工環保.在化工和能源開發制造行業，泄壓閥機被顯示在高溫和性溫度過低下.泵.壓縮成機元件。鋼不適應合焊結。
