Spring Tempered Carbon Steel Wire
What Is Spring Tempered Carbon Steel Wire?
Spring tempered carbon steel wire is a high-carbon steel alloy subjected to specialized heat treatment processes, including quenching and tempering. This treatment enhances its tensile strength, elasticity, and fatigue resistance, making it ideal for springs, fasteners, and other load-bearing components. With a carbon content typically ranging between 0.60% and 1.00%, this wire achieves a perfect balance between hardness and flexibility.
Key Properties
High Tensile Strength
Capable of withstanding extreme stress without deformation.
Superior Elasticity
Returns to its original shape after repeated compression or tension.
Fatigue Resistance
Performs reliably under cyclic loading conditions.
Corrosion Resistance
Optional coatings (e.g., zinc, epoxy) enhance longevity in harsh environments.
Top Applications Across Industries
