Metal forgings
The ability of a metal to undergo plastic deformation under external forces is called forging performance and depends mainly on the plasticity of the metal. The better plasticity, the better the metal forging performance.
After the forging of the metal material, the inner pores can be welded, the fine shrinkage cavity is distributed and the density of the metal is increased, the as-cast columnar crystals and coarse grains are crushed into fine grains, the metal Mechanical properties. Welding performance refers to the adaptability of the metal material to the welding process: Since the welding is an uneven heating process, the metal materials with good thermal conductivity and small shrinkage have better welding performance. Good welding performance, the metal can be guaranteed after welding the shape and size of the same, does not produce the weld, and welded joints have sufficient strength.

Machining performance refers to the ease of cutting metal materials.
Hard to cut metal, poor processing performance; easy cutting metal, good processing performance. The cutting performance is related to the chemical composition, microstructure, mechanical properties, thermal conductivity and deformation enhancement of the material. Especially the hardness of the material has a great influence on it. Generally, the hardness of the material is the best when it is processed from 160 to 230hb. Good performance of metal cutting tool wear small, good surface quality after processing, cutting force, less power consumption.
