38B2 wire is a high-quality alloy structural steel wire. It has good hardenability, ensuring uniform performance after heat treatment. After proper treatment, it can have high strength and can withstand large loads. It has excellent processing performance and is suitable for cold heading, cold extrusion and other processes, and can be processed into various complex parts. Wires of different diameters are stable in mechanical properties, and the tensile strength and cross-sectional shrinkage can meet the actual application requirements.

38B2 wire has become a popular material choice in many fields due to its excellent performance and wide applicability.
