S40C wire is a high-quality carbon structural steel wire. S40C wire has high strength and good toughness, can withstand large loads, is not prone to brittle fracture when subjected to force, and can adapt to different working environments to provide reliable support for various mechanical structures. At the same time, it has good machinability, is easy to machine, and can be processed into parts of various complex shapes. The cold deformation plasticity is moderate, and a certain degree of shaping can be performed through cold processing to meet different design requirements. S40C wire has become an ideal choice for many industries with its excellent performance and wide applicability.
