Duplex Steel S32205 Rods are highly sought after across various sectors due to their remarkable properties and versatility. S32205 is a duplex stainless steel that synergizes the advantages of austenitic and ferritic stainless steels, resulting in unparalleled strength, corrosion resistance, and cost efficiency. Composition and Property: Duplex steel S32205 comprises approximately 22% chromium, 5-6% nickel, 3% molybdenum, and significant levels of nitrogen, endowing it with robust corrosion resistance and impressive strength. The dual-phase microstructure of austenite and ferrite yields superior mechanical properties compared to traditional austenitic or ferritic stainless steels. Corrosion Resistance: A standout feature of S32205 rods is their high resistance to various forms of corrosion. They exhibit excellent resistance to pitting and crevice corrosion in chloride environments, making them perfect for use in corrosive settings such as chemical processing, marine environments, and the offshore oil and gas industry.

Duplex 2205 Round Bar is a high-performance duplex ferritic-austenitic stainless steel bar with an impressive composition of 22% chromium, 3% molybdenum, and 5-6% nickel. As the most widely utilized duplex stainless steel grade, it boasts a yield strength that is double that of traditional austenitic grades. Its robust construction ensures superb fatigue strength and exceptional resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion, even in the harshest environments.
Manufacturers generally recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece is not compact, the edges might cool faster than the bulk, potentially causing cracking in cooler regions.
Duplex 2205 demonstrates excellent formability in various fabrications. However, its high strength may pose challenges, necessitating equipment with sufficient power and allowing for higher spring-back due to the grade's strength.
Duplex stainless steel bar 2205 presents a slight challenge compared to the 300 series austenitic stainless steel. This grade requires higher cutting forces, leading to quicker tool wear. To achieve optimal results, adhere to these machining guidelines: A) Employ a robust, rigid machine with a strong and secure tool and workpiece mount; B) Keep tool extensions minimal to reduce vibrations; C) Maintain a tool nose radius that is as short as possible to ensure carbide sharpness while providing sufficient strength; D) Sequence machining operations so that the depth of cut always penetrates beneath the work-hardened layer from the preceding step.
