Features
product presentation
Cold drawn high carbon spring steel wire is a high carbon steel (usually with a carbon content of 0.45% -1.0%) processed through precision cold drawing technology, which has ultra-high strength, excellent elasticity, and fatigue resistance. Its microstructure has been specially treated with highly refined grains, making it suitable for manufacturing spring components with strict requirements for accuracy and durability. It is a core material in industrial equipment, automobiles, machinery, and other fields.
Core advantages
High strength and high elastic limit
The tensile strength can reach 1600-2200 MPa, and the elastic recovery rate is>99%, ensuring the long-term stable operation of the spring.
Excellent anti fatigue life
After millions of cycles of testing, it has excellent anti relaxation performance and extended the service life of components.
Precision dimensional control
Strict tolerance (± 0.02mm), smooth surface (Ra ≤ 0.2 μ m), reducing machining losses.
