What are the excellent characteristics of forgings?
Release time:
2024-11-27
For metal components, there are generally two methods: casting and forging. Casting is mainly suitable for the production of components that do not have high precision and quality requirements. However, forging is different; forged parts are superior to cast parts because casting does not change the original microstructure and mechanical properties of the metal. The fibrous structure increases the strength and toughness of the metal, making it very suitable for wear-prone components. Additionally, forged parts are more conducive to operations such as welding, deformation, and plasticity, and their performance does not change significantly after these processes. Therefore, forged parts are widely used in modern industry.

At the same time, forged parts are more conducive to welding, deformation, and plasticity operations, and their performance does not change significantly after these processes. Therefore, the application of forged parts in modern industry is very widespread.
However, currently, forged parts have higher requirements for equipment. The larger the scale of the forged parts, the higher the requirements for the equipment. There are still significant difficulties in the manufacturing of forging equipment in the country. Although there have been breakthroughs, there is still a considerable gap from the world's advanced level. Therefore, when choosing forged parts, it is important to select forging factories with strong capabilities to ensure quality.
Stainless steel can improve its microstructure and mechanical properties after forging. The cast structure undergoes thermal processing and deformation through forging methods, resulting in the transformation of the original coarse dendrites and columnar grains into finer, uniformly sized equiaxed recrystallized structures. This process compresses and welds the original segregation, porosity, and inclusions within the steel ingot, making the structure denser and improving the metal's plasticity and mechanical properties. It ensures that forged parts have good mechanical properties and a long service life. Forged parts produced using precision die forging, warm extrusion, and other processes are unmatched by cast parts.
