3.0mm 70# high-carbon mechanical spring wire

3.0mm 70# mechanical spring steel wire, a type of high-carbon steel wire, is precisely crafted through a precise cold drawing process. The advanced technology ensures the high quality of the product. This product features outstanding performance, with a tensile strength ranging from 1850 to 2150MPa and excellent elastic properties, maintaining good elasticity throughout long-term use. The diameter tolerance is strictly controlled within ±0.02mm, with precise dimensions, high surface finish, stable bending and torsional performance, and is convenient for processing into various required spring shapes. It has a wide range of applications and plays a significant role in scenarios such as industrial door springs and fitness equipment components, especially in situations where high durability and deformation recovery capabilities are required. For instance, this type of steel wire can be used in resistance ropes, resistance springs, the elastic system of rowing machines, and traction sprin…
