What is Duplex 2205 / UNS S32205 Round Bar?

Duplex steels combine the best properties of both ferritic and austenitic stainless steels, resulting in materials with enhanced durability and corrosion resistance. A duplex steel round bar, especially the duplex 2205 round bar, features a dual-phase microstructure strengthened with nitrogen for even better mechanical performance. Unlike fully austenitic grades like 304 or solely ferritic grades like 430, duplex round bar and 2205 round bar offer a balanced solution, making them a top choice for demanding applications where both strength and corrosion resistance are required. The duplex steel bar category includes materials that don't fit entirely within the traditional austenitic or ferritic families, bridging the gap for enhanced versatility and performance.
