Import 65mn Alloy Steel Strip/Coils — Buy in Bulk from Supplier in China

The 65Mn alloy steel strip and coils are cold-rolled, hardened, and tempered spring steel products designed for applications demanding high tensile strength and resilience. This grade is a manganese-enhanced carbon steel, offering superior hardness and elasticity compared to standard carbon steels. The material is supplied in coil or strip form, with precise dimensional control to meet tight tolerances for mechanical components.

Compositionally, 65Mn contains approximately 0.62-0.70% carbon and 0.90-1.20% manganese, delivering a balance of toughness and wear resistance. Typical industry standards for this grade include a tensile strength of 980-1200 MPa and a yield strength of 800-1000 MPa, with hardness values in the 45-50 HRC range after heat treatment. Surface finish is cold-rolled to a smooth, uniform texture, suitable for high-stress applications where fatigue resistance is critical.

Primary buyers include manufacturers of automotive springs, industrial blades, and precision tools. The material is often sourced for use in clutch discs, valve springs, and saw blades due to its ability to retain shape under cyclic loading. Importers should confirm coil width, thickness, and heat treatment state, as these directly impact performance in end-use applications. Standard packaging is steel strapping with moisture barriers to prevent corrosion during transit.

Taian Henson Metal Co., Ltd. is a China-based supplier specializing in cold-rolled alloy and carbon steel products. The company operates from Taian, a region known for its metalworking industry, and focuses on serving international buyers with spring steel and high-strength strip materials. Its profile indicates an imported supplier tier with a harbor trust level, signaling established trade routes but limited direct verification signals.

The supplier’s listing does not specify response metrics, certifications, or operational scale, so buyers are advised to request documentation directly. No claims are made about production capacity, client base, or quality management systems beyond the product specifications provided. Importers should verify compliance with relevant standards (e.g., GB/T 1554 or equivalent) and request mill test certificates for critical applications.
