冷庫保溫隔熱板的表層1.4313是馬氏體級，耐灼傷性強，熱辦公后耐久度性好。X3CrNiMo13-4鋼的設備裝備能是考慮到化學式因素中鉬和鎳的高水平。這樣合金鋼增長劑束縛了上升級碳水平的應該——給定濃度值相同于奧氏體冷庫保溫隔熱板的表層。其實鎳水平較低，但鎳水平約為4%，差異性提高自己了鋼對各式灼傷壞境的減緩力——二級設備裝備能。X3CrNiMo13-4鋼客戶可生產可以達到300℃在攝氏度下辦公的配件上的和配件上的，與露出在各式灼傷壞境中的配件上的，與此同時控制任何的表層前提生活條件括抗氯化物物理性質)。QT650.QT780和QT900前提生活條件下，熱辦公后通常交由工字鋼。半樣品采用石化生產.化工公司.在冶金機械和資源行業內，渦輪機機露出在高輕柔超高溫下.泵.解冰柜壓縮機零配件。鋼不舒適合手工焊接。
