The advantages of forgings mainly include the following aspects:
High strength and good mechanical properties: During the forging process, the metal forms a fibrous grain structure under the action of force. This structure is relatively dense and can improve the strength and hardness of the forging. In addition, forging can reduce or eliminate metallurgical defects that may exist in the raw materials, such as cracks, hot cracks, cold shuts, etc., minimize the porosity of the product, and improve the mechanical properties of the product and the stability of product quality between different batches. Good plasticity and toughness: During the forging process, the grains of the metal are refined as the metal is deformed, thereby improving the ductility and toughness of the forged parts and reducing their brittleness. The forged parts have good impact resistance and fatigue resistance. Compared with machining or casting methods, the strength and toughness of forged parts can be increased by 30%. Uniform internal organization: During the forging process, the grain flow of the metal will bend to follow the contour of the forging shape, strengthen directionally, and produce high-quality parts. This directional grain flow makes forgings more resistant to stress corrosion cracking.
Wide range of applications: The mass of forgings can range from less than 1kg to hundreds of tons, and can be produced in single pieces, small batches, or large batches. In addition, precision die forging can make the size and shape of forgings close to finished parts, saving metal materials and reducing cutting processing time.
