Daftar Isi:
- It has been related the effect of holding time heating, quenching, and tempering of influence in the leaf spring steel AISI No. 9260. The research was conducted to determine the impact value of leaf springs steel that are usually used on motor vehicles based on the heating, quenching with oil, and tempering to produce data on the impact of leaf springs steel. Heating process is carried out at a temperature 780 °C with holding time of 40 and 60 minutes the next rapidly cold using oil. The process of heating changes the steel phase to hardly martensite and followed by tempering at a temperature of 600 °C with a holding time of 40 minutes which is made the steel phase transformed into tempered martensite and ferrite, so that the steel hardness decreased and increased impact values. Before doing the heating, the impact values of steel is 0.23 J/mm2 smaller than the steel has been given the heating, quenching, and tempering that is equal to 0.803 J/mm2.
