DESCRIPTION
Medium carbon ferromanganese has a higher content of carbon, carbon is a solid solution element, can increase the hardness and strength of steel. In the medium carbon ferromanganese, the content of carbon reaches a certain proportion, and a certain amount of martensite can be formed. Martensite is a kind of crystal structure with higher hardness and strength, so the medium carbon ferromanganese has higher strength.
The content of manganese in middle carbon ferromanganese is higher, manganese is a strengthening element, can enhance the strength and wear resistance of the metal. Manganese in steel is mainly solidly dissolved in iron matrix to form a strengthened solid solution, and can also combine with carbon to form hard carbides. These hard carbides can increase the hardness and strength of steel, but also can improve the wear resistance and fatigue resistance of steel.
Medium carbon ferromanganese can be heat treated to increase its strength and hardness. In the heat treatment process, the middle carbon ferromanganese will experience a series of heating, insulation, cooling and other processes, these processes can change the structure of the middle carbon ferromanganese, so as to change its mechanical properties. For example, quenched medium carbon ferromanganese can form martensite, resulting in higher hardness and strength.
