316 stainless steel mesh is a woven or welded mesh made from AISI 316 austenitic stainless steel, renowned for its superior corrosion resistance, especially in harsh chemical and marine environments. It is the go-to choice when standard 304 stainless steel isn’t resistant enough.
Key Features of 316 Stainless Steel Mesh:
Material Composition (UNS S31600 / AISI 316)
– Chromium (16-18%) → Provides oxidation & rust resistance.
– Nickel (10-14%) → Enhances ductility and toughness.
– Molybdenum (2-3%) ⭐ Key Advantage! → Boosts resistance to chlorides, acids, and pitting corrosion.
– Carbon (≤0.08%) → Low carbon improves weldability (316L variant has even lower carbon).
– Iron (Balance) → Maintains structural strength.
Corrosion Resistance (Best in Class for Common Stainless Steels)
✔ Excellent in seawater & salt spray (marine applications).
✔ Resists sulfuric, phosphoric, and acetic acids (chemical processing).
✔ Performs well in chloride-rich environments (unlike 304).
✔ Better than 904L in some cases (but 904L excels in extreme acids).
Temperature Resistance
– Continuous Use: Up to 870°C (1600°F) (similar to 304).
– Not for extreme heat (use 310, 330, or Inconel above 900°C).
– Weave Types:
– Plain Weave (most common for filtration).
– Twill Weave (stronger, smoother surface).
– Dutch Weave (ultra-fine filtration).
– Welded Mesh (rigid, structural use).
– Mesh Sizes: From ultra-fine (400+ mesh) to coarse (1/4″ openings).
– Wire Diameter: Adjustable for strength vs. airflow (e.g., thin wires for filters, thick for screens).
Top Applications of 316 Stainless Steel Mesh:
Marine & Offshore
– Saltwater filtration, boat screens, underwater components.
– Desalination plants & offshore oil rigs.
Chemical & Pharmaceutical
– Acid-resistant filters, reactor screens, pharmaceutical sieves.
– PPE equipment (breathing filters, chemical splash guards).
Food & Beverage Processing
– Brewery filters, dairy processing, food-grade sieves.
– FDA-compliant (non-reactive with food acids).
Medical & Surgical
– Implantable mesh, sterilization trays, surgical screens.
– Biocompatible (ISO 10993 certified in 316L form).
Architectural & Decorative
– Balcony screens, façade cladding (coastal areas).
– Art installations (rust-proof in humid climates).
316 vs. Other Stainless Steel Meshes:
Property | 316 Mesh | 304 Mesh | 904L Mesh | 310 Mesh |
Corrosion Resistance | ⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐⭐ |
Chloride Resistance | ⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ | ⭐ |
High-Temp Use | ⭐⭐ | ⭐⭐ | ⭐⭐ | ⭐⭐⭐⭐⭐ |
Cost | $$$ | $$ | $$$$$ | $$$ |
When to Choose 316 Mesh?
– Marine, chemical, or acidic environments.
– Long-term outdoor exposure (coastal areas).
– When 304 isn’t corrosion-resistant enough.
When to Avoid 316?
– Extreme heat (use 310/330).
– Ultra-high acid resistance needed (904L is better).
Fabrication & Maintenance Tips:
– Welding: Use 316L filler wire to prevent carbide precipitation.
– Cleaning: Passivate with nitric acid to restore corrosion resistance.
– Avoid Contamination: Keep away from carbon steel tools (prevents rust transfer).
Standards & Equivalent Grades:
– UNS S31600 (Standard 316)
– UNS S31603 (316L – Low Carbon, better for welding)
– EN 1.4401 (316) / 1.4404 (316L) (European)
– AISI 316 (Common U.S. designation)
Final Conclusion:
316 stainless steel mesh is the gold standard for corrosion resistance in marine, chemical, and medical applications. If you need long-lasting performance in harsh environments, this is the best balance of cost vs. durability.
For even harsher conditions (e.g., sulfuric acid, seawater + heat), consider 904L. For extreme heat (furnaces, exhausts), 310 or 330 is better.
