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 is a key process that uses external force to induce plastic deformation of metal blanks to obtain parts with desired shape, size and performance. As the three core forging processes, hot forging, cold forging and warm forging have significant differences in process characteristics, applicable materials and application scenarios due to different processing temperatures. Reasonable selection of process type is crucial for improving part quality and reducing production costs. The following analyzes the differences and suitable scenarios of the three from core dimensions.

Forging quality directly determines the reliability and service life of end equipment. Especially in high-end fields such as aerospace and automotive, the requirements for forging quality are extremely strict. Accurately identifying the superiority of forgings requires considering both appearance integrity and internal performance, to avoid potential safety hazards caused by surface defects or substandard mechanical properties. This article sorts out 4 core identification methods, progressing from appearance to performance, to help quickly and accurately judge the quality of forging processing.
