一般規定從工件表層深入到半馬氏體區(馬氏體與非馬氏體組織各占一半的地方易測定硬度)的深度為淬硬層深度。淬硬層越深,就表明GB9948石油裂化管的淬透性越好 ,如果淬硬層深度達到心部,則表明該鋼全部淬透。 
  GB9948石油裂化管的淬透性好壞對機械性能影響很大,但并非所有的機械零件都必須完全淬透。例如,承受彎、扭應力的軸類零件,表面熱處理的零件等,只需要一定深度的淬硬層就已滿足使用要求。 
  GB9948石油裂化管的淬透性主要決定于臨界冷卻速度,臨界冷卻速度越小,GB9948石油裂化管的淬透性就越好,反之,則降低GB9948石油裂化管的淬透性。除Co以外,大多數合金元素都能顯著提高鋼的淬透性。 
  應當注意的是,淬透性和淬硬性是兩個不同的概念,不可混淆。淬硬性是指淬火后獲得的最高硬度,主要取決于馬氏體中的含碳量。淬透性好的GB9948石油裂化管,它的淬硬性不一定高。如高碳工具鋼與低碳合金鋼相比,前者淬硬性高但淬透性低,后者淬硬性低但淬透性高。
