| Abstract: | Through experiments,the production process of 16MnCrS5 steel bars for precision turning is determined,and the appropriate sulfur content,cooling speed and annealing temperature parameters are studied to meet the requirements of high-end automotive pin precision turning parts. The results show that the tested 16MnCrS5 steel hot-rolled bars with S content ranging from 0.028% to 0.035% were cooled at a cooling rate of 1.37 to 1.69 ℃/s,and then subjected to stress relief annealing at 620 ℃ for 6 h in a continuous annealing furnace,and the hardness was 180-215 HBW which met customer requirements of that for stress relief annealing precision turning bar. |
