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.

During the forging processing, cracks and oxidation are the most common quality defects. They not only affect the mechanical properties and service life of forgings, but may also lead to product rejection and increase production costs. Clarifying the causes of these two types of defects and adopting targeted solutions are the key to improving forging quality and reducing loss. 

Forging processing is a core manufacturing process that obtains parts with the required shape, size and performance by applying external force to cause plastic deformation of metal blanks. It is widely used in various industries such as machinery, mining, automotive, aerospace and so on. Mastering its process principles and core technical points is the key to ensuring forging quality, improving production efficiency and reducing processing costs. Combining with practical operation scenarios, this article sorts out the core content to help industry practitioners gain an in-depth understanding.
