Import 65mn Cold Rolled Spring Steel Strip With Hardene — Buy in Bulk from Supplier in China

The 65Mn Cold Rolled Spring Steel Strip With Hardene from Taian Henson Metal Co., Ltd. is a high-carbon steel strip supplied in hardened and tempered condition. It is produced from 65Mn steel, a grade recognised for its manganese content that improves hardenability and wear resistance. The strip is cold rolled to achieve precise thickness and width tolerances, with a smooth surface finish suitable for further processing such as blanking, forming, or coating. The hardening process enhances its elasticity and fatigue strength, making it ideal for dynamic load applications.

This spring steel strip typically conforms to GB/T 1222 or equivalent international standards for 65Mn grade, with a carbon content around 0.62 to 0.70% and manganese around 0.90 to 1.20%. The material offers a tensile strength typically in the range of 980 to 1275 MPa after heat treatment, with elongation values that ensure resilience under cyclic stress. Standard surface finishes include a bright, oiled, or phosphate-coated finish to prevent corrosion during storage and transit. Coil or cut-to-length options are typical, with widths ranging from 10 mm to 600 mm and thicknesses from 0.1 mm to 3.0 mm depending on the application.

Primary buyers include manufacturers in the automotive, agricultural machinery, and construction sectors, where the strip is used for leaf springs, torsion bars, and clip components. The material’s ability to retain shape under repeated stress makes it a preferred choice for suspension systems and mechanical fasteners. Trade terms such as FOB and CIF are available, with packaging usually in coiled form wrapped in moisture-resistant material. Buyers should confirm exact dimensions, heat treatment status, and surface protection requirements before ordering to ensure compatibility with their production lines.

Taian Henson Metal Co., Ltd. is a China-based supplier specialising in steel products, including spring steel strips. The company operates as an imported-tier supplier, indicating it sources materials for international trade. Its profile does not state a response rate or average response time, so buyers should expect to follow up directly for technical or commercial queries.

The supplier’s focus appears to be on providing industrial-grade steel materials to manufacturers in sectors such as automotive and machinery. No additional details on certifications, production capacity, or facility specifics are provided in the listing. Buyers are advised to request verification of quality control processes, such as heat treatment records or third-party test reports, to confirm the strip meets their application requirements.
