Premium AISI 1070 Spring Steel Strip – Engineered for Performance
As a leading 1070 steel strip supplier, we provide precision cold rolled steel strip with consistent hardness and superior surface finish. Our AISI 1070 grade is engineered for excellent heat treatment response, making it the ideal choice for high-strength springs, durable blades, and critical automotive components. Available in custom coil or cut-to-length formats.
Advantage
Optimal Composition: Standard AISI 1070 chemical composition (0.65-0.75% Carbon) ensures a perfect balance of strength, hardness, and manageable toughness.
Superior Process State: Supplied in cold rolled or annealed condition, offering tight tolerances and excellent dimensional stability for precision stamping and forming.
Exceptional Hardenability: Responds predictably to quenching and tempering, allowing you to achieve target hardness (typically HRC 50-60 after treatment) for wear-resistant parts.
Proven Applications: The go-to material for spring steel strips, knife blades, industrial cutting tools, scrapers, and various high-stress automotive parts.
Customization Ready: We supply 1070 steel strip in a wide range of thicknesses and widths. Request a quote for your specific requirements.
