Product Description
Haokun's series of Forging refers to the workpiece or blank obtained by forging and deforming the metal blank. The mechanical properties can be changed by applying pressure to the metal blank to produce plastic deformation. Forgings can be divided into cold forging, warm forging, and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the metal blank.
