Are you looking for a material that bridges the gap between ferritic and austenitic steels? Duplex 2205 SS is the industry standard for demanding environments. At Salem Stainless Steel Suppliers Pvt. Ltd., we provide high-grade S31803/S32205 solutions that deliver double the strength of conventional stainless steels and exceptional resistance to localized corrosion.
Duplex 2205 Stainless Steel Sheet is a nitrogen-enhanced stainless steel developed to solve common corrosion problems found in the 300-series grades. Its unique microstructure – roughly 50% austenite and 50% ferrite – offers the “best of both worlds.”
| Feature | The Duplex 2205 Advantage |
|---|---|
| Durability | High resistance to stress corrosion cracking (SCC). |
| Strength | Significantly higher yield strength than 304 or 316 grades. |
| Stability | Chromium and Molybdenum content prevents pitting and crevice corrosion. |
| Economy | High strength often allows for thinner, lighter, and more cost-effective designs. |
Chemical and Metallurgical Advantages of SS Duplex 2205 Sheets:
The superior performance of Duplex 2205 SS comes from its alloy composition:
- Chromium forms a protective oxide passivation layer, enhancing corrosion resistance.
- Molybdenum improves resistance to pitting and crevice corrosion.
- Nitrogen increases strength and prevents brittleness.
- Balanced ferrite-austenite structure enhances mechanical properties.
This combination allows Duplex 2205 SS sheets to perform exceptionally well even in high-oxidation and chloride-rich environments.
At Salem Stainless Steel Suppliers Pvt. Ltd., we bridge the gap between engineering requirements and high-performance materials. Below is the technical breakdown of our Duplex 2205 (S32205/S31803) inventory, sourced from the world’s leading manufacturers.
