Specialist Stainless Steel
SS 300 Series Roller Chains
The Donghua SS 300 Series is the industrial standard for applications requiring maximum corrosion resistance. Manufactured entirely from high-grade stainless steel, this series is specifically designed for the food and beverage, pharmaceutical, and marine sectors where hygiene and environmental resilience are non-negotiable. While standard steel chains fail in wet or acidic conditions, the SS 300 series maintains structural integrity and prevents contamination.

Applications and use
The SS 300 series is the primary choice for environments where carbon steel or coated chains would suffer premature oxidation. We have found repeatedly in conversations with customers that in high corrosive environments the SS-300 can outperform the SS+ 400.
Key applications are:
Marine & Saltwater
Using the SS316 variant for ultimate chloride protection.
Food Processing
Ideal for washdown zones and non-contact food environments.
Chemical & Pharma
Resistant to harsh cleaning agents and sterile requirements.
Textile & Sanitation
Handles high humidity and constant exposure to fluids.

Standards, naming, and interchangeability
The SS 300 series is built to international standards, ensuring compatibility with standard sprockets.
- Standards: Manufactured in accordance with ISO 606[cite: 4, 6].
- Pre-Tensioning: All chains are pre-tensioned at 40 – 50% of the breaking load to minimise initial stretch.
- Design: Features solid bush and solid roller construction for a robust mechanical profile.
How to identify your chain:
- Locate the reference number on the side plate (e.g., 08B or 10B).
- Measure the pitch (P) — the distance between pin centres.
- Confirm the material; the SS 300 series will have a distinct stainless steel finish compared to standard steel.

FAQ
Is the SS 300 series pre-lubricated?
No, the SS 300 series is not pre-lubricated as standard. Food-grade or alternative lubrication can be applied upon request.
Should I choose SS304 or SS316?
SS304 is excellent for general corrosive environments. However, SS316 is the best solution for saltwater and chloride-rich environments.
Can this chain operate in extreme heat?
Yes, the 300 series is rated for a temperature range of -40°C to +400°C.
What is the difference between SS 300 and SS+ 400?
The SS 300 series offers superior corrosion resistance. The SS+ 400 series uses hard-chromized pins to provide 30% better wear resistance but has slightly lower chemical resistance.
Are custom lengths available for Swiss delivery?
Yes, we provide fast delivery across Switzerland and can cut chains to your specific requirements. Choose Corsair today!
