Duplex Steel S32205 Rods are utilized across a myriad of sectors owing to their superb characteristics and remarkable versatility. S32205 is a duplex stainless steel that masterfully merges the benefits of austenitic and ferritic stainless steels, delivering exceptional strength, unparalleled corrosion resistance, and remarkable cost efficiency. Composition and Property: Duplex steel S32205 boasts approximately 22% chromium, 5-6% nickel, 3% molybdenum, and elevated levels of nitrogen, which collectively contribute to its formidable corrosion resistance and strength. The dual-phase microstructure of austenite and ferrite significantly surpasses the mechanical properties of conventional austenitic or ferritic stainless steels. Corrosion Resistance: One of the most notable features of the S32205 rod is its robust resistance to various forms of corrosion. It is highly resistant to pitting and crevice corrosion in chloride environments, making it an ideal choice for application in corrosive settings such as chemical processing, marine environments, and the offshore oil and gas industry.

Duplex 2205 Round Bar is a remarkable duplex ferritic-austenitic stainless steel bar, enriched with 22% chromium, 3% molybdenum, and 5-6% nickel. This makes it the most widely utilized duplex stainless steel grade, boasting a yield strength that is double that of conventional austenitic grades. It excels in fatigue strength and exhibits outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion even in the most demanding conditions.
Most producers of Duplex 2205 recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the workpiece shape is not compact, the edges may cool significantly faster than the bulk, risking cracks in the cooler regions.
Duplex 2205 demonstrates good formability across various fabrications. However, its high strength can pose challenges. Even if the equipment has enough power, allowances must be made for higher spring-back due to the grade's elevated strength.
Crafting excellence in machining, the Duplex Stainless Steel Bar 2205 embodies a slight challenge compared to the 300 series austenitic stainless steels, demanding greater cutting forces and consequently experiencing quicker tool wear. Elevate your machining experience with these pivotal guidelines: A) Employ a robust, rigid machine coupled with an exceptionally strong tool and workpiece mount; B) Minimize vibration by keeping tool extensions short; C) Maintain a precise tool nose radius to ensure the carbide retains a sharp edge while sustaining necessary strength; D) Strategically design the machining sequence to ensure every cut depth remains beneath the work-hardened layer from preceding operations.
