Welcome to Hemaokang Steel (Shandong) Co., Ltd., your trusted partner in high-quality stainless steel solutions. Our 316L Stainless Steel Coil 0.8mm Thick is specifically engineered for pharmaceutical equipment fabrication, offering exceptional corrosion resistance, durability, and hygiene compliance. With our ISO9001-certified production processes and a strong export track record exceeding USD 50 million annually, we deliver precision coils that meet the most demanding industry standards. This product is the ideal choice for manufacturers seeking reliable, long-lasting materials for cleanroom environments, storage tanks, piping systems, and processing machinery.
Our 316L coil features a low carbon content (max 0.03%) which minimizes carbide precipitation during welding, ensuring superior intergranular corrosion resistance. The 0.8mm thickness provides a perfect balance between strength and formability, making it suitable for complex geometries in pharmaceutical equipment. Each coil is produced under strict quality control, with surface finishes available in 2B, BA, No.4, or HL to suit different aesthetic and functional requirements. Width can be customized to your specifications, from 1000mm to 1500mm, or as per your drawing.
Key Product Features & Technical Specifications
- Material Grade: 316L (UNS S31603 / EN 1.4404) – low carbon austenitic stainless steel, resistant to chlorides, acids, and alkalis commonly found in pharmaceutical environments.
- Thickness Tolerance: ±0.05mm, ensuring precise fabrication without additional machining.
- Surface Finish Options: 2B (standard cold-rolled, bright), BA (bright annealed, mirror-like), No.4 (brushed, 120 grit), HL (hairline). All finishes are free of surface defects and meet cleanroom standards.
- Mechanical Properties: Tensile strength ≥ 485 MPa, Yield strength ≥ 170 MPa, Elongation ≥ 40% – providing excellent ductility for bending, stamping, and deep drawing.
- Corrosion Resistance: Excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, thanks to 2–3% molybdenum content.
- Weldability: Low carbon content prevents sensitization, allowing welding without post-weld heat treatment. Suitable for TIG, MIG, and laser welding.
- Hygiene & Cleanability: Non-porous surface, easy to sterilize, compliant with FDA and GMP guidelines for pharmaceutical contact surfaces.
- Customization: Width, coil ID, surface finish, and edge trimming (slit or mill edge) are available upon request.

The 316L grade is particularly advantageous for pharmaceutical applications because it resists the aggressive cleaning agents (e.g., peracetic acid, hydrogen peroxide) used in sterilization cycles. Our coils undergo rigorous testing for chemical composition, mechanical properties, and surface quality, ensuring every batch meets the strictest requirements. The 0.8mm thickness is widely used for fabricating pressure vessels, fermenters, heat exchangers, and storage tanks where weight reduction is beneficial without compromising structural integrity.

Frequently Asked Questions
Q1: Why is 316L preferred over 304 for pharmaceutical equipment?
A: 316L contains molybdenum (2-3%), which provides superior resistance to chlorides, acids, and pitting. In pharmaceutical environments, exposure to cleaning agents and saline solutions makes 316L more durable and hygienic. The low carbon content also prevents sensitization during welding, ensuring long-term corrosion resistance.
Q2: What is the exact thickness tolerance of your 0.8mm coil?
A: Our thickness tolerance is ±0.05mm, which is tighter than the ASTM A480 standard (±0.10mm). This precision ensures consistent forming and reduces scrap during fabrication.
Q3: Can you supply coils with a specific surface finish for cleanroom applications?
A: Yes. We offer 2B (standard cold-rolled), BA (bright annealed), No.4 (brushed), and HL (hairline) finishes. For pharmaceutical use, we recommend 2B or BA for their smooth, non-porous surfaces that are easy to clean and sterilize. Custom surface roughness (Ra values) can be arranged.
Q4: Do you provide mill test certificates (MTC) for each coil?
A: Absolutely. Every coil comes with a Mill Test Certificate (MTC) showing chemical composition, mechanical properties, and hardness. Third-party inspection by SGS, BV, or TÜV is also available at cost.
Q5: What is the typical lead time for this product?
A: Standard lead time is 15–20 working days after order confirmation. For urgent orders, we can expedite production to 10–12 days, subject to stock availability. We maintain a buffer inventory of popular sizes.
Q6: How do you ensure the material is free from surface defects?
A: Our production line includes online surface inspection using laser sensors and visual inspection under controlled lighting. Additionally, we perform eddy current testing (ECT) on request to detect subsurface defects. All coils are edge-trimmed to remove slit edge burrs.
Q7: Can you cut the coil into sheets or strips?
A: Yes. We offer slitting services to produce custom-width strips, and shearing to produce sheets. Please specify your dimensions when ordering. Minimum order quantity for slitting is 1 ton per width.
Q8: What is your minimum order quantity (MOQ) for 316L 0.8mm coil?
A: Our standard MOQ is 3 tons per size/surface finish. For trial orders, we accept 1 ton at a slightly higher unit price. Contact our sales team for details.
