Blue carbon steel coil is a cold-rolled, hot-tempered, and hardened carbon steel product with a distinctive blue oxide finish, available in thicknesses from 0.25mm to 2.50mm and widths ranging from 40mm to 250mm. The material grades supplied include 50#, 65Mn, 60Si2Mn, and T8A-T10A, each selected for their hardness and spring characteristics. This product is not coated or plated but features a controlled oxide layer formed during heat treatment, providing mild corrosion resistance and a non-reflective surface suitable for precision machining.
The steel composition aligns with standard Chinese GB/T 699 for carbon structural steel and GB/T 1222 for spring steel. Grade 65Mn offers high tensile strength and fatigue resistance, while T8A-T10A provides enhanced wear resistance for cutting tools. Typical yield strength ranges from 800 to 1200 MPa depending on tempering temperature, and the material is supplied with a round edge to reduce handling damage. Oil coating is applied to prevent oxidation during transit, and the coils are packed with plastic film inside and gunny bags outside, mounted on iron pallets for stability.
This product is primarily purchased by manufacturers of hand tools, automotive clutch components, clockwork springs, and industrial blades. Buyers in North America, Europe, and Southeast Asia source it for downstream slitting, stamping, and heat treatment operations. The minimum order quantity is 5 metric tons, with individual coils weighing between 45kg and 100kg. Lead time is approximately 30 days after deposit receipt, and the product is shipped under FOB or CIF terms from Chinese ports.

Linyi Liangyu Steel Strip Co., Ltd is based in Taiping Town, Hedong District, Linyi, Shandong Province, China. The company operates as a manufacturer of cold-rolled and heat-treated steel strips, with a focus on spring and tooling-grade carbon steel products. Its listing indicates it is an imported supplier with harbor-level trust verification, suggesting it has completed basic export compliance checks but has no publicly disclosed certifications or third-party audits.
The supplier does not claim to be a distributor, exporter, or certified producer. No information is provided regarding factory size, workforce, years in operation, or client list. The absence of response rate or average response time suggests limited buyer communication infrastructure. The product range is narrow, centered on blue carbon steel coils, indicating a specialized production line rather than a broad steel distributor.
Blue carbon steel coil is a specialty flat-rolled carbon steel product with a distinctive blue oxide finish, available in thicknesses from 0.25 to 2.50mm and widths of 40 to 250mm. Grades include 50#, 65Mn, 60Si2Mn, and T8A-T10A, commonly used in spring manufacturing, tool-making, and industrial blade production. This product is widely sourced by importers in the automotive, tooling, and hardware industries seeking competitively priced Chinese-manufactured steel coils for further processing.

Before placing an order, verify the chemical composition of the specified grade (e.g., 65Mn or T8A) through a mill test report. Confirm the hardness range and tensile strength align with your application requirements, especially if the material will undergo secondary heat treatment. Request proof of consistent thickness tolerance across the coil width, as deviations beyond ±0.05mm can cause feeding issues in stamping machines.
Lead time is stated as 30 days after deposit, but confirm whether this includes production, inspection, and customs clearance. Clarify the Incoterms - FOB or CIF - and ensure the port of loading matches your freight forwarder’s network. Payment terms are not specified; negotiate against a 30% deposit and 70% against shipping documents to reduce risk. Confirm coil weight per unit and pallet configuration to ensure compatibility with your warehouse handling equipment.
Perform incoming quality checks for surface integrity, including uniformity of the blue oxide layer and absence of scratches or rust spots. Use a magnet to test for non-magnetic contamination, which may indicate improper heat treatment. Inspect packaging for moisture ingress, especially if the coils will be stored before use. Request batch-specific MTRs and retain samples for future reference if the material is used in safety-critical components.
