不透鋼1.4313是馬氏體級，耐氧化性好，感應加熱后耐用性好。X3CrNiMo13-4鋼的機設備制造能力是因為普通機的成分中鉬和鎳的高純度。這類耐熱合金調用劑制約了擴大級碳純度的必須要 ——給定濃硫酸濃度等同于于奧氏體不透鋼。總之鎳純度不夠，但鎳純度約為4%，差異性提高自己了鋼對各式氧化室內環境的抗力——重新機設備制造能力。X3CrNiMo13-4鋼玩家可加工的萬代高達300℃在溫下崗位的機件和機件，與暴曬在各式氧化室內環境中的機件，一起維持充足的表層情況括抗氯化物類別)。QT650.QT780和QT900情況下，感應加熱后通常交盤鋼管。半原材料中用石油天然氣加工的.精細化工.在化工和能源資源業，增壓機暴曬在高一個溫和低溫下.泵.降低機元器件。鋼惡化的情況合氬弧焊。
