Import Cold Work Steel — Buy in Bulk from Supplier in China

Shenzhen Zhaoheng Specialty Steel Co., Ltd supplies cold work steel in a variety of bar shapes, including flat bars sized 8‑90 mm in width and 305‑610 mm in length, as well as round bars ranging from 8 mm to 1000 mm in diameter. The supplier describes the alloy as delivering high hardness and excellent machinability, and notes that it conforms to international standards such as ISO and BIS. No specific chemical composition is listed, but the grade aligns with typical O2 cold‑work steel properties commonly used in tooling applications.

Typical O2‑type cold work steel attains a hardness of 58‑64 HRC after oil‑quench and tempering, providing the wear resistance required for high‑stress moulds and dies. The material’s density is around 7.7 g/cm³ and it exhibits a thermal expansion coefficient near 11 × 10⁻⁶ /°C, matching standard industry figures. Standard machining practices yield good chip breakability, allowing efficient production of complex geometries without excessive tool wear.

The steel is marketed to manufacturers in the automotive, tool‑making and general engineering sectors who need reliable, hard‑facing material for cold‑work applications. While the listing does not specify a minimum order quantity, buyers are invited to discuss bulk volumes and receive a customised quotation. Potential importers should confirm the applicable Incoterms, payment conditions and any required certifications before finalising a purchase.

Shenzhen Zhaoheng Specialty Steel Co., Ltd is situated at F/17 Unit A, Jinfengcheng Building, Shennan East Road, Shenzhen, Guangdong, China. The company is listed as an imported‑tier supplier with a harbor trust tier, and the platform records show a response rate of 0 % and no average response time, indicating that communication may require proactive follow‑up.

The supplier’s catalogue highlights cold work steel in multiple bar formats, emphasizing high hardness, good machinability and compliance with ISO and BIS standards. No details on production capacity, lead‑time or pricing are disclosed, so interested buyers should request a formal quotation and technical data sheet to assess suitability.
