Description
Summary:This study aims to examine the effect of holding time on the microstructure and mechanical properties of 13% medium manganese steel with variations in cooling. The temperature used is the austenitizing temperature of 800°C with variations of holding time of 15, 30, and 45 minutes with variations of water quenching and air cooling. The choice of cooling variation aims to determine the phase change in the microstructure and its effect on mechanical properties. The results of the hardness test obtained the highest value on the specimen holding time of 15 minutes with air cooling of 371.5 BHN, and the lowest value on the specimen holding time of 45 minutes with air cooling of 253.5 BHN. Tensile test results obtained the highest value at the specimen holding time of 15 minutes with air cooling of 1090 MPa, and the lowest value at specimen holding time of 45 minutes with air cooling of 926 MPa. The results of elongation obtained the highest value on specimen holding time of 45 minutes with 88% air cooling, and the lowest value on specimen holding time of 15 minutes with 40% air cooling. Holding time affects the hardness and mechanical properties of 13% medium manganese steel.
