Hemaokang Steel (Shandong) Co., Ltd., established in 2025, is a rapidly growing supplier of high-quality stainless steel products. With an annual export value exceeding US$50 million and a dedicated team of 51–100 employees, we are proud to offer our 316L Stainless Steel Coil, Cold Rolled, 0.5mm–3.0mm Thickness, 1000mm–1500mm Width, with 2B Finish — a product specifically engineered for the demanding requirements of the chemical industry. Our coil combines superior corrosion resistance, excellent formability, and consistent mechanical properties, making it an ideal choice for chemical processing equipment, storage tanks, and piping systems. Backed by our ISO9001:2015 certified quality management system, we ensure every coil meets international standards and delivers long-term reliability.
Key Features & Technical Specifications
Our 316L stainless steel coil is produced through a cold rolling process, which ensures precise thickness control, a smooth surface, and enhanced mechanical strength. The 2B finish provides a bright, reflective surface suitable for most industrial applications without requiring additional polishing. Below are the core technical parameters:
| Parameter | Specification |
|---|---|
| Grade | 316L (UNS S31603) |
| Thickness | 0.5 mm – 3.0 mm (±0.02 mm tolerance) |
| Width | 1000 mm – 1500 mm (±1 mm tolerance) |
| Surface Finish | 2B (cold rolled, bright annealed, light skin pass) |
| Standard | ASTM A240 / A240M, EN 10088-2, JIS G4304 |
| Coil Weight | 3 – 8 tons per coil (customizable) |
| Edge | Slit edge or mill edge (available upon request) |
| Coil Inner Diameter | 508 mm or 610 mm (optional) |
Superior Performance for the Chemical Industry
The 316L grade contains molybdenum (2–3%), which significantly improves resistance to chloride ion corrosion — a common challenge in chemical environments. Compared to standard 304 stainless steel, 316L offers:
- Enhanced pitting and crevice corrosion resistance in acidic and chloride-rich media.
- Lower carbon content (≤0.03%) reduces the risk of sensitization during welding, maintaining corrosion resistance in heat-affected zones.
- Excellent formability and weldability — suitable for bending, stamping, and roll forming.
- Consistent mechanical properties: tensile strength ≥485 MPa, yield strength ≥170 MPa, elongation ≥40%.
- 2B finish provides a smooth, non-porous surface that minimizes adherence of chemical residues and simplifies cleaning procedures.
These characteristics make our coil ideal for chemical reactors, heat exchangers, storage tanks, pipelines, and valve components where exposure to aggressive media is routine. By using our 316L coil, customers can achieve longer equipment service life and reduced maintenance costs.
Quality Control & Customization
Every coil undergoes rigorous inspection at our facility in Liaocheng, Shandong, China. Our ISO9001-certified quality management system ensures:
- 100% dimensional inspection for thickness, width, and flatness.
- Surface quality check under controlled lighting.
- Mechanical testing (tensile, yield, elongation) on each production batch.
- Chemical composition analysis via spectrometer to verify grade 316L.
- Intergranular corrosion test per ASTM A262 (available upon request).
We also offer customization options including different widths, thicknesses, coil weights, and edge types. For special requirements such as pickling & passivation or protective film coating, please contact our sales team.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 316L and 316 stainless steel?
A: 316L has a lower carbon content (≤0.03%) compared to 316 (≤0.08%). This reduces the risk of carbide precipitation during welding, making 316L more suitable for welded applications where corrosion resistance is critical. -
Q: Can you supply coils with other surface finishes, such as No.1 or BA?
A: Yes, we can produce coils with different surface finishes (No.1, BA, 2D, etc.) upon request. Please provide your specific requirements for a customized solution. -
Q: What is the minimum order quantity (MOQ) for this 316L coil?
A: Our standard MOQ is 5 tons per size. However, we can accommodate smaller trial orders for new customers. Contact our sales team for details. -
Q: How do you package the coils for export?
A: Coils are packed with anti-rust paper, plastic film, and steel bundling to protect against moisture and damage during transit. Sea-worthy wooden pallets or crates are used as needed. -
Q: What is the typical lead time for an order?
A: For standard sizes, lead time is 15–25 days after receipt of deposit. Custom orders may require 25–35 days. We always strive to meet urgent deadlines. -
Q: Do you provide test certificates or mill test reports?
A: Yes, we provide a Mill Test Certificate (MTC) per EN 10204 Type 3.1 for every shipment. Third-party inspection (e.g., SGS, BV) is also available at extra cost. -
Q: Is your 316L coil suitable for high-temperature applications?
A: 316L maintains good oxidation resistance up to about 870°C in intermittent service and 800°C in continuous service. For higher temperatures, consider 310S or 321 grades. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer free samples (exclusive of shipping costs) for quality evaluation. Please provide your delivery address and we will arrange shipment.
