Import 62si2mna Hign Strength Steel Strip — Buy in Bulk from Supplier in China

The 62Si2MnA is a silicon-manganese spring steel strip supplied by Taian Henson Metal Co., Ltd., designed for applications requiring high elastic limits and fatigue resistance. This grade is cold-rolled to precise thickness tolerances, delivering a minimum tensile strength of 1200 MPa and a yield strength of 1100 MPa, with elongation at break typically between 5 and 8 percent in the as-rolled condition. The material conforms to GB/T 1222 and is offered in coil or cut-to-length formats, with widths from 10 mm to 300 mm and thicknesses from 0.1 mm to 3.0 mm as per buyer specification.

Silicon and manganese are the primary alloying elements, with silicon content standard around 1.5 to 2.0 percent and manganese standard around 0.6 to 0.9 percent, balances optimized for spring applications. Surface finishes include black, cold-rolled, or pickled and oiled, with a typical roughness Ra of 1.6 µm or better for precision uses. The steel is supplied in the annealed or hardened and tempered state, with hardness values standard in the range of 44 to 52 HRC depending on heat treatment.

This strip is used in automotive suspension systems, valve springs, and mechanical components like clutches and brake springs where cyclic loading is common. Buyers in the machinery and tooling sectors source it for blades, saws, and high-stress fasteners. Taian Henson Metal Co., Ltd. confirms availability in coil weights up to 5 tonnes, with packaging in steel strapped bundles or wooden crates for export. Lead times and incoterms are negotiated per order, with FOB Qingdao a common request.

Taian Henson Metal Co., Ltd. is based in Taian, Shandong Province, China, and operates as a specialized supplier of alloy and spring steel products to international buyers. The company’s profile indicates it is categorized as an imported-tier supplier with a harbor trust tier, reflecting its role in cross-border trade. While the response rate and average response hours are currently unavailable, the listing confirms its focus on industrial-grade materials for demanding applications.

The supplier’s product range includes high-strength steel strips like 62Si2MnA, alongside other grades such as 65Mn, 1065, and SAE1055, catering to sectors like automotive, construction, and machinery. The profile does not state certifications, production capacity, or client references, so buyers are advised to request these details directly. The absence of verified response metrics suggests confirming communication channels and trade terms before proceeding with orders.
