As a trusted manufacturer from Hemaokang Steel (Shandong) Co., Ltd., we are proud to introduce our 316L Stainless Steel Plate for Pharmaceutical Equipment with a 2B surface finish, 1.5mm thickness, and specially cleaned and passivated to meet the stringent requirements of the pharmaceutical industry. With over 50 employees and an annual export value of US$50 million to US$100 million, our company is dedicated to delivering high-quality stainless steel products that ensure safety, durability, and compliance. This plate is engineered to resist corrosion, withstand harsh cleaning agents, and maintain a smooth, non-porous surface ideal for sterile environments.
Our 2B surface finish provides a bright, reflective appearance that is both aesthetically pleasing and easy to clean, while the 1.5mm thickness offers an excellent balance between strength and formability. The cleaning and passivation process removes surface contaminants and forms a protective chromium oxide layer, enhancing the material's natural corrosion resistance. This makes the plate particularly suitable for pharmaceutical equipment such as tanks, vessels, piping, and cleanroom installations where hygiene and product integrity are paramount.
Below are the key technical specifications of our 316L stainless steel plate:
| Specification | Detail |
| Material Grade | 316L (UNS S31603) |
| Thickness (Nominal) | 1.5 mm (0.059 inch) |
| Surface Finish | 2B (cold rolled, bright annealed) |
| Tolerance (Thickness) | ±0.05 mm (standard) |
| Width Range | 1000 mm – 2000 mm (customizable) |
| Length Range | 2000 mm – 6000 mm (customizable) |
| Surface Roughness (Ra) | ≤ 0.5 μm (typical) |
| Passivation Process | Citric acid or nitric acid (compliant) |
| Certification | ISO9001:2015 |
Key Advantages for Your Business:
- Superior Corrosion Resistance – The low carbon content (316L) minimizes carbide precipitation during welding, ensuring excellent resistance to intergranular corrosion in aggressive pharmaceutical environments.
- Hygienic & Easy to Clean – The 2B surface finish is smooth and non-porous, preventing bacterial growth and allowing for quick sterilization with CIP (Clean-in-Place) systems.
- Precision Thickness Control – Our 1.5mm plates are manufactured with tight tolerances (±0.05mm), providing consistent performance in fabrication and assembly.
- Enhanced Surface Integrity – The cleaning and passivation treatment removes iron contaminants and restores the passive film, extending the service life of equipment and reducing maintenance costs.
- Versatile Application – Ideal for pharmaceutical reactors, storage tanks, transfer lines, isolators, and other critical equipment requiring high purity and durability.
- Customizable Dimensions – We offer flexible sizing options to meet your specific project requirements, reducing waste and optimizing material usage.

Frequently Asked Questions
-
Q: What is the difference between 316 and 316L stainless steel?
A: The key difference is the carbon content. 316L has a lower carbon (max 0.03%) which reduces the risk of carbide precipitation during welding, making it more resistant to intergranular corrosion – critical for pharmaceutical equipment that undergoes frequent sterilization. -
Q: Why is the 2B surface finish recommended for pharmaceutical applications?
A: The 2B finish is cold-rolled, annealed, and lightly polished to produce a smooth, reflective surface with low roughness. This minimizes dirt adhesion and makes cleaning easier, meeting the high hygiene standards of cleanrooms and sterile processing areas. -
Q: What does “cleaned and passivated” mean for this plate?
A: Cleaning removes grease, oil, and other contaminants from the surface. Passivation then chemically treats the surface to form a thin, protective chromium oxide layer that enhances corrosion resistance. This process is essential for preventing rust and maintaining long-term performance in aggressive environments. -
Q: Can you provide custom sizes besides the standard 1.5mm thickness?
A: Yes, we offer customizable widths and lengths to suit your specific needs. Thickness variations (e.g., 1.0mm, 2.0mm) are also available upon request. Please contact our sales team for detailed specifications. -
Q: Is this plate suitable for welding without affecting its corrosion resistance?
A: Absolutely. The low carbon content of 316L minimizes sensitization during welding, so the heat-affected zone maintains good corrosion resistance. We recommend using proper welding procedures and post-weld passivation if required. -
Q: What certifications do you provide with the product?
A: We provide an ISO9001 certificate for our quality management system. Additionally, we can supply mill test certificates (MTC) reflecting chemical composition and mechanical properties per ASTM A240 or relevant standards upon request. -
Q: How is the plate packaged for export?
A: Each plate is interleaved with protective paper or plastic film, securely bundled with steel straps, and packed in wooden crates or pallets to prevent damage during transit. We ensure proper labeling and documentation for efficient customs clearance. -
Q: What is the typical lead time for orders?
A: For standard sizes, lead time is usually 15–25 working days. Custom orders may require 20–30 working days depending on quantity and specifications. We work closely with logistics partners to ensure timely delivery worldwide.
