The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.
亚温正火温度对40SiMnCrNiMoA的组织和硬度等性能的影响的实验研究表明，当亚温正火保温温度为760℃时，复合组织中的铁素体形态是块状，处理后的材料硬度相对较低（HRC32左右）；而当采用大于800℃温度亚温正火处理，材料硬度为HRC49左右，组织中铁素体大部分较连续地存在于原奥氏体的晶界，对材料强化不利；当40SiMnCrNiMoA钢780℃亚温正火后，硬度为HRC38左右，在以往小钎杆较长寿命所需硬度范围HRC35-40内，而组织为细条状铁素体+以板条马氏体和条状无碳贝氏体为主的复合组织，晶粒细小均匀，铁素体体积含量少于20％。
