Hot forging and cold forging are two core processes in metal forging. Both realize plastic deformation of metals through pressure to optimize the mechanical properties of parts. However, they differ significantly in processing temperature, forming principles, process characteristics and application scenarios. Reasonable process selection according to the working conditions, accuracy and strength requirements of products can effectively improve the quality of forgings and control production costs, serving as a key basis for type selection in industrial forging production.

Metal forging is a precision processing technology that uses pressure equipment to apply impact force or pressure on metal blanks, causing plastic deformation of metals to obtain finished forgings. As one of the core processes in mechanical manufacturing, forging differs from casting molding. It can optimize the internal microstructure of metals and greatly improve the comprehensive mechanical properties of parts. It is widely used in the manufacturing of high-strength parts for heavy machinery, wind power equipment, mining accessories, automobile parts and other fields.

I. Common Forging Materials

Forged parts are essential basic mechanical components in modern industrial production. Made from metal raw materials through forging, hammering and pressure forming processes, they are widely used in heavy industry, machinery, metallurgy, energy, hydraulic equipment and other fields, serving as core accessories to ensure stable equipment operation. Compared with ordinary castings and plate-processed parts, forged parts feature a denser structure and more stable performance due to unique forming characteristics.

In harsh industrial scenarios such as heavy machinery, metallurgical equipment, energy engineering, and hydraulic transmission, the stability of parts directly determines the operational safety and service life of equipment. With excellent comprehensive performance, high-strength forgings feature high pressure resistance, high temperature resistance and non-deformation characteristics. They are perfectly suitable for various heavy-load, high-temperature and high-pressure working conditions, serving as core load-bearing and transmission parts for industrial equipment and widely favored by various industries.
