Characteristics
High wear resistance, can be vacuum heat treated to 100%, and has excellent processing performance.
Heat treatment process
Heat treatment method
After rough machining of the stress-relieved annealed workpiece, it is heated to ~℃, kept warm, cooled to ℃ with the furnace, and air-cooled out of the furnace.
The quenched workpiece is slowly heated to ℃, and the temperature is maintained for the first time to preheat. After equalizing, the temperature rises to ℃, and then the temperature is maintained for the second preheating. Finally, the temperature is raised to ℃, kept warm, and air-cooled after leaving the furnace.
Tempering should be tempered immediately after quenching, and tempered at least twice, and the holding time each time should not be less than
Heat treatment precautions
Tempering should be done in time after quenching to prevent cracking, and to To prevent surface decarburization, gauges and high-precision molds should be cryogenically treated (°C), and high-temperature tempering should be used to reduce workpiece deformation. High-temperature tempering temperature ~°C, hardness, large annealing indentation diameter. Quenching,
