304不銹鋼管1.4313是馬氏體級，耐腐化高，熱除理后耐久度性好。X3CrNiMo13-4鋼的機戒穩定性是因催化有效成分中鉬和鎳的高份量。許多耐熱合金加入劑受到限制了不斷增加級碳份量的都要——給定溶液濃度該是于奧氏體304不銹鋼管。雖然說鎳份量不太高，但鎳份量約為4%，不錯增加了鋼對各樣腐化生活要求的抗力——三次機戒穩定性。X3CrNiMo13-4鋼用戶數可產生銷售更是高達300℃在溫差下工作的的加工組件和加工組件，還有曝露在各樣腐化生活要求中的加工組件，一并保護一定的單單從表面生活要求括抗氯化物特征)。QT650.QT780和QT900生活要求下，熱除理后最易交樓鋼材。半制成品用作油田產生銷售.礦業.在礦冶和能量餐飲行業，渦輪增壓機曝露在高輕柔超低溫下.泵.降低機零配件。鋼不舒適焊接方法。
