Daftar Isi:
- With the development of technology in manufacturing, the need to use steel material as the base material of a tool or product increasingly diverse. Annealing election itself constituted to reduce the hardness of materials, creating a material that is soft, but has a high degree of ductility in the material, in this case steel AISI 1045. Effect of heat treatment Annealing is to improve toughness and reduce brittleness of the material. the material used in this test is the steel AISI 1045 carbon steel was classified. which has the properties of hardness and resistance to the suppression of material. The goal is to determine the characteristics of the mechanical properties of the steel material used. Also to determine the characteristics of the microstructure of the steel before and after the annealing process. Annealing process at a temperature of 850 ° C with a variation of holding time 15, 30, 45 and 60 minutes. and testing the chemical composition, Rockwell hardness testing, bending testing, and Micrography testing. The test results generated at the highest hardness test material raw material with hardness HRB 88.8. The maximum bending stress there is in the test sample holding time of 60 minutes at 1980.01 N / mm2.
