Duplex Steel S32205 rods are highly versatile and used across a multitude of sectors due to their exceptional characteristics. S32205 is a duplex stainless steel that merges the advantages of both austenitic and ferritic stainless steels, ensuring remarkable strength, superior corrosion resistance, and cost efficiency. Composition and Property: Duplex steel S32205 consists of approximately 22% chromium, 5-6% nickel, 3% molybdenum, and elevated nitrogen levels, offering both robust corrosion resistance and strength. The dual-phase microstructure of austenite and ferrite surpasses the mechanical properties of traditional austenitic or ferritic stainless steels. Corrosion Resistance: A standout feature of S32205 rods is their high resistance to various types of corrosion, specifically pitting and crevice corrosion in chloride environments, making them ideal for sectors such as chemical processing, maritime environments, and offshore oil and gas industries.

Duplex 2205 Round Bar is an exceptional duplex ferritic-austenitic stainless steel bar, boasting a composition of 22% chromium, 3% molybdenum, and 5-6% nickel. As the most widely used duplex stainless steel grade, it offers double the yield strength of standard austenitic grades. It stands out for its impressive fatigue resistance and unparalleled resilience against stress corrosion, cracking, crevice corrosion, pitting, erosion, and general corrosion in the harshest of environments.
Most producers recommend a hot forming temperature between 2010 and 2100°F (1100 to 1150°C). Non-compact shapes may have cooler edges, risking cracking in these regions.
Duplex 2205, renowned for its impressive formability across various fabrications, presents certain challenges due to its high strength. Even with powerful equipment, allowances must be made for the increased spring-back inherent to this grade, ensuring precision and reliability in every application.
Machining Duplex stainless steel bar 2205 requires more effort compared to 300 series austenitic stainless steel. The increased cutting forces lead to quicker tool wear. To optimize machining: A) Employ a robust, rigid machine with strong tool and workpiece mounts; B) Minimize tool extensions to reduce vibration; C) Use the smallest necessary tool nose radius to maintain a sharp carbide edge while ensuring adequate strength; D) Plan the machining sequence to keep the depth of cut below the work-hardened layer from the previous operation.
