304 vs 316 Stainless Steel Perforated Sheets
| Feature | 304 Stainless Steel | 316 Stainless Steel |
|---|---|---|
| Corrosion Resistance | Good (general use) | Excellent (marine/chemical environments) |
| Cost | More economical | Higher price due to molybdenum content |
| Applications | Industrial, architectural | Marine, chemical, high-corrosion environments |
| Maintenance | Easy | Easy, slightly more resistant to harsh conditions |
Choose 304 for standard industrial and architectural use. Opt for 316 if your project involves marine or chemical exposure.

FAQ for 304 Stainless Steel Perforated Sheets
Can 304 perforated sheets be used outdoors?
es, 304 performs excellently in most outdoor environments. However, for coastal areas with high salt-spray exposure, we recommend upgrading to our [316 Stainless Steel Perforated Sheets].
What is the most common hole size for filtration?
This depends on your specific medium. Typically, round holes with a 2mm-5mm diameter are popular for general filtration tasks.
What industries commonly use 304 perforated sheets?
Industrial filtration, architecture, furniture, construction, and machine guarding.
Can I order custom sizes and hole patterns?
Yes, we can manufacture sheets to any size and hole pattern per your requirements.
What is the difference between 304 and 304L for perforated panels?
304L is the low-carbon version of 304. We recommend 304L if your project requires extensive welding, as it prevents carbide precipitation and ensures the joints remain as corrosion-resistant as the rest of the sheet. For decorative or light-load tasks, standard 304 is usually sufficient.
Can 304 perforated stainless steel be powder coated or PVD colored?
Absolutely. While 304 has a beautiful natural metallic finish (2B or Brushed), it is highly receptive to PVD coating (Gold, Rose Gold, Black) and powder coating. This is a popular choice for architectural facades and interior partitions where branding or aesthetics are key.
Is 304 perforated sheet magnetic?
Standard 304 stainless steel is generally non-magnetic in its annealed state. However, the mechanical punching process (cold working) can introduce a slight magnetic response. If your application requires strictly zero magnetism, please let us know so we can provide the appropriate solution.
How do I calculate the open area for my 304 perforated sheet?
The opening area depends on the aperture (D) and the aperture spacing (P). For a standard 60-degree staggered circular aperture arrangement, the formula is: Opening Area % = (D² × 90.69) / P². If you have any questions, please contact our engineers, and we will provide accurate calculations based on your airflow or filtration needs.
What is the minimum hole size possible for a 3mm thick 304 sheet?
Generally, to avoid tool damage, the hole diameter should not be less than the sheet thickness. For 3 mm thick sheets, we recommend a minimum hole diameter of 3 mm. For micro-hole machining needs, please consult our laser drilling service.
How do you prevent burrs on the perforated surface?
We use high-quality tungsten steel dies and perform post-production deburring and polishing. This ensures the 304 sheets are smooth to the touch, which is critical for food processing and public installations.
