Duplex Steel S32205 Rods are essential in numerous sectors due to their superior attributes and versatility. S32205 is a duplex stainless steel that merges the advantages of austenitic and ferritic stainless steels, providing remarkable strength, corrosion resistance, and cost efficiency. Composition and Property: Duplex steel S32205 contains approximately 22% chromium, 5-6% nickel, 3% molybdenum, and high levels of nitrogen, contributing to its exceptional corrosion resistance and strength. The dual-phase microstructure of austenite and ferrite offers superior mechanical properties over traditional austenitic or ferritic stainless steels. Corrosion Resistance: A standout feature of S32205 rod is its robust resistance to various forms of corrosion. It excels against pitting and crevice corrosion in chloride environments, making it perfect for use in corrosive settings such as chemical processing, maritime, and offshore oil and gas industries.

Duplex 2205 Round Bar stands as a duplex ferritic-austenitic stainless steel bar, comprised of 22% chromium, 3% molybdenum, and 5-6% nickel. It holds the title as the most widely-utilized duplex stainless steel grade, boasting a yield strength that is double that of standard austenitic grades. This remarkable steel also showcases exceptional fatigue strength and unwavering resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion even in the harshest conditions.
Most producers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece is not compact, the edges may cool significantly faster than the bulk, risking cracking in these cooler regions.
The Duplex 2205 stainless steel exhibits remarkable formability across various fabrications. However, its impressive high strength can present challenges. Even with powerful equipment, it's crucial to account for a greater spring-back due to the grade's robustness.
Machining the Duplex 2205 stainless steel bar is slightly more demanding than working with the 300 series austenitic stainless steels. It requires greater cutting forces, which lead to quicker tool wear. Follow these machining guidelines: A) Employ a powerful, rigid machine with robust tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Keep the tool nose radius as short as necessary to maintain a sharp carbide edge while ensuring strength; D) Sequence machining operations so that the cutting depth consistently stays below the work-hardened layer from previous steps.
