Welcome to Hemaokang Steel (Shandong) Co., Ltd. — your reliable partner for high-quality steel solutions. We are proud to present our ±0.05mm Thickness Tolerance Low Carbon Steel Coil ASTM A1008, engineered specifically for precision parts manufacturing. With our state-of-the-art production lines and strict quality control, we ensure every coil meets the most demanding dimensional accuracy requirements. Our company, established in 2025, has rapidly grown to achieve an annual export value of US$50 million to US$100 million, serving clients across North America, South America, Europe, Asia, and Africa. This product is a testament to our commitment to precision and reliability.
This low carbon steel coil is manufactured in accordance with the ASTM A1008 standard, which guarantees consistent mechanical properties and formability. The ultra-tight thickness tolerance of ±0.05mm is critical for applications where even minor deviations can lead to product failure. Whether you are stamping, bending, or deep drawing, our coil delivers uniform thickness and excellent surface quality, reducing scrap rates and improving production efficiency.
Key Features & Benefits
- Exceptional Thickness Accuracy: ±0.05mm tolerance ensures consistent part dimensions, eliminating the need for secondary machining.
- ASTM A1008 Compliance: Full compliance with international standards for low carbon steel, guaranteeing mechanical properties like yield strength, tensile strength, and elongation.
- Excellent Formability: Low carbon content (typically ≤0.15%) makes the coil ideal for deep drawing, bending, and stamping without cracking.
- Uniform Surface Finish: Pickled and oiled surface (optional) provides clean, rust-resistant material for immediate processing.
- Customizable Dimensions: Width from 600mm to 1500mm, coil weight up to 15 tons, and slit or mill edge options to match your specific needs.
- ISO9001 Certified Quality: Our production processes are ISO9001:2015 certified, ensuring traceability and consistent quality batch after batch.
- Cost-Effective: Reduced material waste and higher yield due to precise thickness control directly lower your production costs.

Why Choose Our Low Carbon Steel Coil for Precision Parts?
Precision parts demand materials that offer consistency, reliability, and tight tolerances. Our coil is specifically designed to meet these requirements. The ±0.05mm thickness tolerance is one of the tightest in the industry, allowing you to produce parts with minimal variation. This is especially critical in industries such as automotive components, electronic connectors, home appliance parts, and medical devices. By using our coil, you can achieve tighter assembly fits, reduce rework, and enhance the overall quality of your final products.
Additionally, the low carbon content ensures excellent weldability and formability, making it suitable for complex shapes. The material is also compatible with coatings like galvanizing or painting, giving you flexibility in downstream processes. With our ISO9001 certified quality management system, every coil is tested for mechanical properties, surface defects, and dimensional accuracy before shipment. We also provide mill test certificates (MTC) with each order for full traceability.
Frequently Asked Questions (FAQ)
Q1: What is the exact thickness tolerance of this coil?
A: The standard thickness tolerance is ±0.05mm for the entire range. For specific thicknesses, please contact us to confirm.
Q2: Can this coil be used for deep drawing applications?
A: Yes, the low carbon content and excellent formability make it suitable for deep drawing. We recommend performing a trial based on your specific die design.
Q3: Is the coil surface treated to prevent rust?
A: We offer pickled and oiled (P&O) surface treatment as a standard option, which provides temporary corrosion protection. Other surface treatments like dry or phosphate coating are available upon request.
Q4: What certifications do you provide?
A: All coils come with a Mill Test Certificate (MTC) showing chemical composition and mechanical properties. Our factory is ISO9001 certified.
Q5: Can you supply coils in slit widths?
A: Absolutely. We can slit the master coil to your required width (minimum 20mm) with a slit edge finish. Tolerance on slit width is ±0.2mm.
Q6: What is the minimum order quantity (MOQ)?
A: Standard MOQ is 20 tons per size. For smaller quantities, please discuss with our sales team — we may accommodate trial orders.
Q7: How long is the lead time?
A: For standard sizes, lead time is 15–20 days after order confirmation. Custom sizes may require 25–30 days.
Q8: Do you offer free samples?
A: Yes, we can provide small samples (e.g., 200mm x 200mm) for quality evaluation. The buyer is responsible for shipping costs.
