65Mn Carbon Steel Strip — Factory Direct Supplier | Huaxia-Steel

65Mn is a high-carbon manganese steel strip known for its excellent elasticity, wear resistance, and fatigue strength after heat treatment. It is widely used for springs, clips, washers, saw blades, and wear-resistant components. Huaxia-Steel supplies cold-rolled and annealed 65Mn carbon steel strip in precise thicknesses and widths, directly from Chinese mills with full material certification.
Product Overview
65Mn carbon steel strip contains approximately 0.62–0.70% carbon and 0.90–1.20% manganese. This combination gives it high hardness and spring-like properties after quenching and tempering. In the annealed condition, the strip is soft and formable, making it ideal for stamping, bending, and forming. After heat treatment, it can reach hardness levels suitable for springs, clips, and cutting tools.

Manufacturing Standards
65Mn strip is produced by hot rolling, cold rolling, annealing, and skin passing. We can supply according to GB/T 1222 for spring steel, GB/T 3275 for rolled quality carbon steel, or JIS G 3311 for cold-rolled special steel strip. Width slitting, edge conditioning, and tension leveling are available to meet tight flatness and coil-set requirements.
Applications
- Flat springs, leaf springs, and clips
- Washers, circlips, and retaining rings
- Knives, saws, and cutting edges
- Shovels, rakes, and hand tools
- Agricultural machinery wear parts
- Automotive seat components and brackets
- Electrical contacts and switch parts

Quality Assurance
Each coil is tested for chemical composition, tensile strength, hardness, and surface quality. Coils are checked for camber, edge cracks, and decarburization. We offer oil-coating, VCI packaging, and rust protection for long sea voyages. Third-party inspection and EN 10204 3.1 certificates are available on request.
Packaging and Shipping
Strips are wound on wooden or steel drums and wrapped with waterproof paper and VCI film. Coils are secured with steel strapping and loaded in wooden crates or pallets. Each shipment is accompanied by a packing list, MTC, and weight ticket. We can arrange container loading, lashing, and insurance for export orders.
