Temper brittleness during forging and processing of forgings
Due to the presence of temper brittleness during forging and processing of forgings, the available tempering temperatures are limited. To prevent brittleness from increasing during tempering, it is necessary to avoid these two temperature ranges, which makes it difficult to adjust mechanical prop...Read more -
What are the heating methods for shaft forgings？
Continuous moving heating is commonly used for induction heating of shaft forgings, while high-frequency quenching heating usually involves fixing the inductor while the forging moves. Medium frequency and power frequency heating, often moved by sensors, and the forging can also rotate when neede...Read more -
