Zeron Fastners
Duplex and Super Duplex Stainless Steels represent the pinnacle of strength and corrosion resistance in the steel family. Zeron Fasteners specializes in grades like UNS S31803 (Duplex) and UNS S32760 (Super Duplex). These materials feature a mixed austenitic-ferritic microstructure, granting them roughly twice the yield strength of standard austenitic steel. Their high content of Chromium, Molybdenum, and Nitrogen provides outstanding resistance to localized corrosion, particularly in chloride-rich environments. They are the ideal choice for demanding applications in offshore oil and gas, chemical processing, and desalination plants.
Key Grades and Properties
| Grade | Microstructure | Key Property | Application Highlight |
|---|---|---|---|
| UNS S31803 / S32205 (Duplex 2205) | Austenitic-Ferritic (50/50) | High Strength, Chloride SCC Resistance | Process Piping, Heat Exchangers |
| UNS S32760 (Super Duplex) | High Mo/N Content | Extreme Pitting/Crevice Corrosion Resistance | Offshore Platforms, Desalination Plants |
