Abstract：The sub-temperature quenching process of 40Cr cutter bar was studied. The results show that: The microstructure is ferrite + tempered martensite and mechanical properties meet technical requirements of the milling cutter bar.The improvement technology saves electric energy, shortens the quenching time, reduces the pollution to the environment, and has obvious economic benefit and promotion value.
