316L Stainless Steel Coil 1.0mm Thick ASTM A240 Standard Mill Test Report Available
Product Spotlights
Hemaokang Steel (Shandong) Co., Ltd. is proud to offer high-quality 316L Stainless Steel Coils with a precise thickness of 1.0mm, manufactured strictly in accordance with ASTM A240 standard. As a newly established ISO9001-certified supplier with an annual export value of US$50 million to US$100 million, we combine competitive pricing with reliable product traceability. Each coil comes with a complete Mill Test Report to ensure full compliance and performance in demanding environments such as chemical processing, marine engineering, and food industry applications.
Our 316L stainless steel coils are characterized by excellent corrosion resistance, especially against chlorides and acidic media, thanks to the low carbon content (max 0.03%) that minimizes sensitization during welding. The 1.0mm thickness is ideal for applications requiring a balance of strength and formability, and the coil format allows for efficient processing in stamping, bending, and roll forming operations. Below we detail the key specifications and advantages.
Key Features & Benefits
- Superior Corrosion Resistance: 316L grade offers enhanced resistance to intergranular corrosion and pitting in chloride environments, making it suitable for coastal and chemical plant settings.
- Precise Thickness Control: 1.0mm ±0.05mm tolerance ensures consistency for downstream fabrication.
- ASTM A240 Compliance: Full adherence to international standard guarantees mechanical properties and chemical composition.
- Mill Test Report Included: Every coil is supplied with a certified test report documenting chemical analysis, tensile strength, yield strength, and elongation.
- Excellent Weldability: Low carbon content reduces carbide precipitation, enabling reliable welding without post-weld heat treatment.
- Customizable Dimensions: Width can be tailored from 1000mm to 1500mm, and coil inner diameter can be 508mm or 610mm to fit your processing equipment.
- Surface Finish Options: Available in 2B (bright, cold-rolled), BA (bright annealed), or No.1 (hot-rolled with pickled finish) upon request.
- Global Delivery: Serving markets across North America, South America, Europe, Asia, Africa, and Oceania with reliable logistics.

Q2: Do you provide free samples for quality evaluation?
A: Yes, we can provide small samples (e.g., 200mm x 200mm) at no cost. The buyer bears the shipping cost. Samples are cut from actual production coils.
Q3: How is the coil packaged to prevent damage during shipping?
A: Each coil is wrapped with moisture-proof paper, plastic film, and steel strapping, then packed in seaworthy wooden crates or pallets. Custom packaging available upon request.
Q4: Can you supply coils with other surface finishes like 2B or BA?
A: Absolutely. The standard finish is 2B, but we also offer BA (bright annealed) and No.1 (hot-rolled pickled) finishes. Please specify your requirement when ordering.
Q5: What is the typical delivery time for a container order?
A: For standard widths and finishes, production takes 15–20 working days. For non-standard sizes, it may be 20–25 working days. Shipping time depends on the destination.
Q6: Do you guarantee that the chemical composition matches ASTM A240?
A: Yes, every coil is tested in our laboratory and a Mill Test Report is issued. The report includes %C, %Mn, %P, %S, %Si, %Cr, %Ni, %Mo, and other elements, ensuring full compliance.
Q7: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment) and L/C at sight. For long-term partners, other terms can be negotiated.
