Abstract
The purpose of this research is to improve the quality of the chisel cutting nails with quenching process using steel AISI 1045 at a temperature of 850°C and 900°C by varying the speed of the cooling medium 3.29 m/s, 0.82 m/s, 0.36 m/s, 0.2 m/s, 0.13 m/s. The method used is the process of heating the specimen at temperatures of 850°C and 900°C with holding time for 30 minutes, then specimen in quenching the cooling medium flowing water and then proceed with the temepering. Hardness testing methods after quenching and tempering is method Cone Hard Rockwell (HRC) and the method is a method Charpy impact testing. The test results obtained in this study, the highest hardness value is at a temperature of 900°C before 3.29 tempered by the cooling speed m/s at 59.8 HRC and impact strength value of 5.73 Nm/mm2. After tempering process value drops to 58.2 HRC hardness and impact strength values rose to 6.28 Nm/mm2. From these results indicate that the AISI 1045 steel can be used as an alternative material to use nail cutter chisel, which uses SKD11 steel with 58-60 HRC hardness value.
