Duplex 2205 Round Bar epitomizes the strength and versatility of duplex ferritic-austenitic stainless steel, boasting an impressive composition of 22% chromium, 3% molybdenum, and 5-6% nickel. Recognized as the most frequently utilized duplex stainless steel grade, it offers a yield strength that is double that of standard austenitic grades. Its exceptional fatigue strength, coupled with unparalleled resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion, makes it indispensable in severe conditions.
Manufacturers typically recommend a maximum hot forming temperature range of 2010 to 2100°F (1100 to 1150°C). For non-compact shapes, the cooler edges pose a risk of cracking, warranting careful monitoring.
Duplex 2205 showcases exceptional formability across diverse fabrications. Despite its impressive strength, the robust nature of Duplex 2205 can present challenges. Even with sufficient power, it necessitates allowances for increased spring-back due to its high strength.
Machining Duplex stainless steel bar 2205 is somewhat more challenging compared to the 300 series austenitic stainless steel. It requires greater cutting forces and results in quicker tool wear. Here are some critical machining guidelines: A) Employ a powerful, rigid machine with a robust tool and workpiece mount; B) Minimize tool extensions to reduce vibration; C) Ensure the tool nose radius is only as long as necessary to maintain a sharp edge while ensuring adequate strength; D) Sequence machining operations to always cut below the work-hardened layer from previous operations.
