Import Cold Rolled C75s Tempered Spring Steel Strip — Buy in Bulk from Supplier in China

The Cold Rolled C75s Tempered Spring Steel Strip is a carbon steel grade designed for high-stress applications that demand consistent elasticity and fatigue resistance. This material is cold-rolled to precise thicknesses and widths, then tempered to achieve uniform hardness across the coil, making it suitable for components that must endure repeated flexing or loading. The strip is supplied in a hardened and tempered condition, ready for immediate use in spring manufacture without additional heat treatment.

C75s steel is a medium-high carbon alloy with typical carbon content of 0.70-0.80% and manganese around 0.60-0.90%, delivering tensile strength in the range of 1000-1200 MPa in the tempered state. Surface finish is standard for cold-rolled strip, with a smooth, slightly matte appearance that meets typical industry standards for spring steel. The material exhibits good formability in the annealed state and high resilience after tempering, with standard tolerances for thickness and width per ASTM A684 or equivalent international norms.

This strip is primarily used in automotive suspension systems, industrial valves, and precision mechanical assemblies where reliable spring performance is critical. Buyers typically source it in coil form for automatic feeding into stamping or roll-forming lines. Sourcing terms should confirm coil weight, inner diameter, and packaging to prevent transit damage, as well as the tempering temperature range to ensure consistency with downstream processing requirements.

Taian Henson Metal Co., Ltd. is a China-based supplier specialising in cold-rolled and tempered spring steel products, with a focus on industrial-grade materials for precision applications. The company operates from Shandong Province, a recognised hub for steel production and metal processing, and offers a range of carbon and alloy steels tailored to automotive and machinery manufacturing requirements.

The supplier is classified as an imported-tier partner, indicating it sources raw materials or intermediate products from international markets to meet specific customer demands. While the company does not disclose verification metrics such as response rates or historical performance data, its profile confirms a focus on spring steel strips, with no additional claims about certifications, client base, or production capacity beyond what is explicitly stated in the listing.
