Physical Properties
Hardened and tempered to its physical properties at room and elevated temperatures.
Welding processing
Taking appropriate protective measures during the welding process of mold steel can achieve good welding results (such as increasing the welding operating temperature, weld preprocessing, appropriate welding rods and welding procedures, etc.). If the mold needs to be polished or photo-etched after repair welding, welding rods with the same chemical composition as the mold steel must be used.
Heat treatment
①Soft annealing is heated to ℃ under a protective atmosphere and then soaked in a furnace at ℃ per hour to ℃ and then air cooled.
② After rough machining, the stress-relieving mold should be heated to ℃ and soaked for two hours, slowly cooled to ℃ and then air-cooled.
③ Hardening (hardening) treatment preheating temperature ℃ austenitizing temperature ℃ is usually selected ℃.
The holding time is the duration after the entire mold is heated to the austenitizing temperature. The mold must be protected during the hardening process to prevent decarburization and oxidation.
④ Quenching medium oil cooling (only suitable for very simple molds). High-speed gas cooling in a vacuum furnace. The flowing air/gas is quenched in a salt furnace or fluidized furnace at ℃ and then air-cooled.
Pay attention to tempering immediately after the mold is cooled to ℃ (all standard size molds can be quenched)
⑤ Tempering and tempering twice and cooling to room temperature after each tempering. The minimum tempering temperature is ℃, each tempering should be kept warm for at least two hours.
⑥Dimensional changes during quenching (sample size mm)
⑦Cryogenic treatment Workpieces with high dimensional stability requirements should be cryogenically treated. This type of treatment is mainly used on gauges and certain structural parts. Immediately after quenching, the workpiece is cooled to a temperature between ℃ and ℃ for an hour and then tempered. The cryogenic treatment can improve the hardness of the workpiece and avoid molds with complex shapes to avoid increasing the risk of cracking. The aging temperature is ℃ and the holding time is hours.
⑧ After nitriding treatment, a hardened layer is formed on the surface of the workpiece, which has high wear resistance and corrosion resistance, and the corrosion resistance is also improved. After nitriding treatment in nitrogen at ℃, the surface hardness of the workpiece is approximately. After two hours of soft nitriding treatment at ℃, the surface hardness of the workpiece is approximately 100 microns.
Electrical discharge machining
If the mold is quenched and tempered and then subjected to electrical discharge machining, one additional tempering should be added and the tempering temperature should be lower than the previous tempering temperature by ℃.
