| Abstract: | This paper introduces a process of high temperature quenching for shooting nailks made of steel 45 and its applications, by which the problems are solved that shooting nails made of steel 45 have not enough toughness and have crack defect, and describes the effect of some processing data, such as the microstructure controlling before quenching, heating temperature, cooling speed, on the toughness and the appearance of cracks.Compared with subnormal temperature quenching, the high temperature quenching process gires the nails good properties and reliability for use and simplifies the whole process.AS a result, this process has high economic and social benefit. |
