Evaluation of Surface Hardness Behavior of Heat-treated 35Mn6Mo3 and C35MN75 Steel
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
The mechanical properties of medium carbon steel (35Mn6Mo3) were investigated. The hardness was tested by Rockwell hardness tester. Samples of medium carbon steel were examined after heating between 9000C-9800C in a vertical force air-circulating furnace and the tempering temperature was 2500C. The hardness values of the quenched samples were relatively higher than those of the as-cast samples. Samples quenched in oil displayed better properties compared with that of water-quenched samples. Water quenched steel produced its best properties in hardness; while oil quenched steel arrived lower hardness compared to water quenching.
