Duplex Steel S32205 Rods are widely utilized across various sectors due to their exceptional properties and versatility. S32205 is a duplex stainless steel that merges the advantages of both austenitic and ferritic stainless steels, offering unparalleled strength, corrosion resistance, and cost efficiency. Composition and Property: Duplex Steel S32205 comprises approximately 22% chromium, 5-6% nickel, 3% molybdenum, and high levels of nitrogen, yielding robust corrosion resistance and strength. This dual-phase microstructure of austenite and ferrite vastly surpasses traditional austenitic or ferritic stainless steels in mechanical properties. Corrosion Resistance: A standout feature of the S32205 rod is its resistance to various forms of corrosion. It shows high resistance to pitting and crevice corrosion in chloride environments, making it perfect for use in corrosive settings such as chemical processing, maritime environments, and offshore oil and gas industries.

Duplex 2205 Round Bar is a high-performance, duplex ferritic-austenitic stainless steel bar enriched with 22% chromium, 3% molybdenum, and 5-6% nickel. Renowned as the most widely utilized duplex stainless steel grade, it boasts yield strength double that of conventional austenitic grades. Its superior fatigue strength and remarkable resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion make it ideal for use in the harshest conditions.
Most producers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece lacks a compact shape, the edges may cool significantly compared to the bulk, posing a risk of cracking.
Duplex 2205 showcases exceptional formability across numerous fabrications, but its inherent high strength can sometimes present challenges. Even with adequately powered equipment, it's essential to account for increased spring-back caused by the grade's robust nature.
Machining Duplex stainless steel bar 2205 is slightly more complex compared to the 300 series austenitic stainless steel. The need for higher cutting forces results in quicker tool wear. Follow these guidelines for effective machining: A) Employ a powerful, rigid machine with a strong tool and workpiece mount; B) Maintain short tool extensions to reduce vibrations; C) Ensure the tool nose radius isn't excessively long, keeping the carbide edge sharp and robust; D) Plan the machining sequence to ensure the depth of cut penetrates below the hardened layer from previous operations.
