Stainless Steel 304 vs 316 Polished Pipe – Which One Should You Choose?
When selecting a polished stainless steel pipe, the choice between SS 304 and SS 316 often depends on the application, corrosion resistance, and cost. At Creative Piping Solutions, we supply both grades in polished finishes like 180, 240, and mirror polish for architectural and sanitary uses.
When to Choose Which?
- Choose SS 304 for general decorative or interior applications with low corrosive exposure.
- Choose SS 316 for coastal, marine, or chemical environments where corrosion risk is high.

Additional Considerations Before You Decide
When comparing Stainless Steel 304 vs 316 polished pipes, also factor in weldability, maintenance, and life cycle cost. Although SS 304 is widely available and economical, SS 316 is preferred in environments exposed to saltwater, acids, and chemicals due to the added Molybdenum, which enhances its resistance to pitting and crevice corrosion.
For high-visibility applications like staircase handrails, glass supports, bollards, and pharma-grade piping, polished pipes not only offer aesthetic appeal but also meet strict hygiene and maintenance requirements.
At Creative Piping Solutions, we ensure every polished pipe meets strict quality control, and we can provide test certificates and finish samples upon request.
Conclusion
Both grades are durable and polish well, but SS 316 is the premium choice where corrosion is a concern. At Creative Piping Solutions, we offer custom lengths and finishes for both grades as per ASTM A554 or equivalent standards.
