Stainless Steel Sheet Grade 316
Stainless Steel Grade 316 sheet is the definitive Marine Grade alloy. While it shares many similarities with the more common Grade 304, the addition of approximately 2-3% Molybdenum significantly enhances its resistance to chlorides, salt spray, and aggressive industrial chemicals.
If your project is located within a coastal region or involves constant exposure to corrosive agents, Grade 316 (also designated as EN 1.4401/1.4404) provides the necessary structural integrity and longevity to prevent pitting and stress-corrosion cracking.

Key Characteristics of Grade 316 Stainless Steel Sheet
- Superior Chloride Resistance: Specifically engineered to thrive in marine environments and de-icing salt exposure.
- Exceptional Chemical Durability: Highly resistant to acetic, sulphuric, and phosphoric acids, making it ideal for pharmaceutical use.
- High Creep Strength: Performs better under mechanical stress at elevated temperatures than Grade 304.
- Aesthetic Longevity: Resists tea-staining and surface rust in outdoor coastal installations.
- Non-Magnetic: Remains non-magnetic in the annealed condition, suitable for sensitive electronic housings.
Common Applications of Grade 316 Stainless Steel Sheet
- Marine Engineering: Boat fittings, deck hardware, and seaside architectural cladding.
- Chemical & Pharmaceutical: Processing vats, storage tanks, and high-purity laboratory surfaces.
- Food Production: Equipment used in the preparation of highly acidic foods or in environments with heavy salt usage.
- Coastal Infrastructure: Public signage, street furniture, and railings in maritime towns.
