High Manganese work hardening Steel Mn13
mn13 high manganese steel is a kind of high hardness... Engineering materials with high wear resistance and good crashworthiness. Heat treatment is one of the important ways to improve its comprehensive properties. below
Is about mn13 high manganese steel heat treatment process research some suggestions:
1 solution treatment: the solution temperature of mn13 high manganese steel is generally between 1050-1100 degrees Celsius, and the holding time should be determined according to the specific situation, usually 1-2 hours. Solid solution
Treatment can effectively eliminate carbides in steel and improve the toughness of steel.
2. Quenching treatment: After solution treatment, mn13 high manganese steel needs to be quenched to improve its hardness and wear resistance. The quenching temperature is usually between 880-930 degrees Celsius,
Cooling medium can be selected oil, water, etc. The choice of quenching speed and cooling medium needs to be adjusted according to the requirements of the specific material and the conditions of use.
3. Tempering treatment: The mn13 high manganese steel after quenching is easy to produce high residual stress, so it is necessary to temper treatment to reduce the residual stress. The tempering temperature is generally
Between 300-600 degrees Celsius, the holding time is determined according to the specific situation. Tempering treatment can improve the toughness and crash-resistance of steel.
4. Surface modification: The surface of mn13 high manganese steel can be welding, chrome plating, spraying and other treatments to improve its wear resistance and corrosion resistance.
It should be noted that the heat treatment process of mn13 high manganese steel needs to be adjusted according to factors such as the composition, structure and use conditions of the specific material, and to test
Certificate. During heat treatment, parameters such as temperature, time and cooling speed need to be controlled to ensure the treatment effect.
