Import Direct Factory High Carbon C75 Sk7 Sk5 — Buy in Bulk from Supplier in China

Direct Factory High Carbon C75, Sk7, and Sk5 steel strips from Taian Henson Metal Co., Ltd. are cold-rolled strips manufactured from high-carbon steel grades with carbon content ranging from 0.70% to 0.80%. These materials are produced to meet DIN 1.2842, JIS SK7, and GB/T 1299 standards for tool steels. The strips are delivered in flat coils with thickness tolerances of ±0.02mm and width tolerances of ±0.5mm, ensuring precision for downstream processing.

The material composition includes manganese at 0.30% to 0.60% and silicon at 0.15% to 0.35%, contributing to hardenability and deoxidation. Surface finish is clean and scale-free, typical of cold-rolled processing, with a Ra surface roughness under 0.8μm. Hardness after annealing is typically 180 to 210 HV, allowing for easy machining before final heat treatment. The strips are free from laminations, seams, or surface cracks that could compromise performance in cutting tools.

This product is used by manufacturers of saw blades, coil springs, die components, and hand tools requiring high wear resistance and edge retention. Buyers typically order in coil weights of 500kg to 1,500kg per reel, with inner diameters of 508mm or 610mm. Trade terms are usually FOB Qingdao or CIF port of destination. Minimum order quantities are negotiable but often start at 2 metric tons. Lead time is approximately 20 to 30 days after receipt of order and deposit.

Taian Henson Metal Co., Ltd. is a manufacturer based in Shandong Province, China, specialising in cold-rolled high-carbon steel strips. The company operates its own rolling and annealing lines and supplies directly to tool and die makers. Its listing reflects verified export history, with a 'harbor' trust tier indicating documented customs clearance and export compliance. No information is provided on annual production volume, workforce size, or certifications such as ISO 9001.

The supplier does not claim proprietary processing methods or exclusive client lists. It does not state whether it performs final heat treatment or surface coating. Its core offering is the delivery of raw material strips to specification. Buyers should confirm whether the material is fully annealed or partially hardened at shipment, as this affects machining behaviour. Response metrics are unavailable, but the supplier's inclusion in export directories suggests active international trade channels.
