The heating temperature of the wear-resistant plate is 810-830 degrees, and the holding time is determined according to the furnace loading method. Tempering temperature: 320 degrees, the time should be sufficient, the oil is cold after tempering, and the tempering brittleness is reduced. The treatment is to pay attention to the deformation of the workpiece, and it is better to have anti-deformation tooling. Better to press quench and press back.

Wear-resistant plate is easy to overheat, pay attention to heating temperature and holding time. Recommended heating 820 degrees, appropriate insulation. Tempering temperature: 320 degrees time to be sufficient. Hardness: 45-48HRC. Good performance. NaCl in salt bath :BaCl=3:7 or so, heating temperature 820, time 30 seconds /mm(mm refers to the effective thickness of parts), oil cold. Tempering temperature 280, air furnace time 2 hours, nitrate furnace time 30 minutes (for reference only, specific temperature and time depending on technical requirements)

To sum up: the temperature of the wear plate should be reasonably controlled, the appropriate temperature should be mastered, and the situation should be processed flexibly!
