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.
