Import Ck75 Carbon Steel Strip — Buy in Bulk from Supplier in China

Ck75 Carbon Steel Strip is a medium-carbon spring steel grade with a carbon content of approximately 0.72% to 0.80%, designed for applications requiring high tensile strength and elastic recovery. This listing confirms availability in thicknesses ranging from 0.3 mm to 3.0 mm, with widths up to 150 mm, and a typical surface finish that is clean and scale-free after cold rolling. The material is supplied in coil form, with inner diameters of 508 mm or 610 mm, consistent with standard industrial handling practices.

Ck75 is a variant within the DIN 1.1221 and JIS SK75 classifications, often compared to SAE 1075 and 65Mn steels. It is not hardened in the as-supplied state but is suitable for subsequent heat treatment such as quenching and tempering to achieve hardness levels between 40 and 50 HRC. The steel exhibits low impurity levels, with sulfur typically under 0.035% and phosphorus under 0.030%, which supports consistent machinability and fatigue resistance. Surface quality is maintained to minimize defects that could initiate cracks under cyclic loading.

This material is commonly purchased by manufacturers of automotive valve springs, precision knife blades, and industrial clamps where consistent elasticity is critical. Buyers in Europe and North America source this strip for replacement parts and custom tooling. Packaging is typically in wooden crates with rust-inhibiting paper, and standard trade terms include FOB Qingdao or CIF destination ports. Minimum order quantities are not specified in the listing and must be confirmed directly with the supplier.

Taian Henson Metal Co., Ltd. is listed as an imported supplier with harbor-tier trust verification, indicating active participation in export logistics and compliance documentation. The company is registered in Taian, Shandong Province, a region known for steel processing and metal distribution. No public details are available regarding factory size, workforce, or years in operation. The listing confirms no response rate or average response time, suggesting communication should be initiated directly through platform channels.

The supplier does not claim certifications, production capacity, or client names. It is not indicated whether the company manufactures the strip in-house or acts as a distributor. Buyers should treat this as a sourcing intermediary unless further verification is obtained. The absence of response metrics does not imply unreliability but requires proactive inquiry to confirm order conditions and material traceability.
