Import C70, C75s, 65mn Blue Spring Steel Strips Harden — Buy in Bulk from Supplier in China

The product consists of C70, C75S and 65Mn blue spring steel strips that have been hardened and tempered for demanding mechanical use. These strips are manufactured from high‑carbon steel grades, delivering high hardness and tensile strength. The supplier offers precision‑cut strips in a variety of widths and thicknesses, all finished with a blue phosphating coating to improve corrosion resistance. Each batch is produced in accordance with recognised ISO and ASTM standards.

In the steel industry, C70, C75S and 65Mn grades are known for hardness values typically between 250 and 300 HB and tensile strengths of 1400‑1800 MPa. The blue finish is a conventional surface treatment that provides a protective barrier without compromising flexibility. Standard tolerances for thickness are usually ±0.05 mm, while width tolerance follows the cut specifications requested by the buyer. These typical parameters make the strips suitable for automotive springs, machinery components and other engineering applications where fatigue resistance is critical.

Buyers commonly source these strips for use in vehicle suspension systems, heavy‑duty springs and precision equipment. The supplier states that flexible minimum order quantities are available and that shipping can be arranged on FOB or CIF terms. Prospective importers should confirm exact MOQ, lead time and payment conditions directly with the supplier before placing an order.
