SWCH10A wire is a high-quality carbon steel wire for cold heading. SWCH10A wire usually has uniform chemical composition and microstructure, and has a good chemical composition ratio, which makes the wire have good comprehensive performance. In addition, the surface is smooth, without defects such as cracks, folds, scratches, etc. The diameter size is relatively precise, and usually has high dimensional accuracy and roundness. It has moderate strength and good plasticity, which enables it to withstand large deformation without cracking during cold heading, while ensuring that the finished product has sufficient strength and toughness; in addition, it also has good machinability and welding performance, which can meet the requirements of various manufacturing processes.
