Premium 1.5mm 80Spring Wire for High-Tension Applications

In the field of precision manufacturing, the selection of materials and the accuracy of process directly determine the upper limit of product performance. This precision spring launched by our factory is based on 80# high-carbon steel as the core substrate and is processed to a standard diameter of 1.5mm through precision cold drawing. With its excellent mechanical properties and stable dimensional accuracy, it has become an ideal choice for high-stress conditions, providing reliable elastic solutions for precision machinery, high-end power tools and key automotive components. As the core support for spring performance, the material advantages of 80# high-carbon steel are particularly prominent. Compared with traditional 70# steel, the carbon content of 80# steel is increased by more than 14%, and the higher carbon proportion gives the material better hardenability. After professional heat treatment, its Rockwell hardness can reach HRC50-55, its tensile strength exceeds 1800MPa, and i…
