Duplex 2205 Round Bar is an exceptional duplex ferritic-austenitic stainless steel bar featuring 22% chromium, 3% molybdenum, and 5-6% nickel. Distinguished as the most widely utilized duplex stainless steel grade, it boasts a yield strength that is double that of standard austenitic grades. This bar excels in fatigue strength and offers remarkable resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion, even in the harshest conditions.
Most producers of Duplex 2205 suggest a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the work piece shape is not compact, the edges may become cooler than the bulk, increasing the risk of cracking in the cooler areas.
Duplex 2205 demonstrates excellent formability across various fabrications, yet its exceptional strength can present challenges. Even with powerful equipment, it's crucial to account for the higher spring-back due to the grade's robust nature.
Machining Duplex stainless steel bar 2205 is slightly more challenging than 300 series austenitic stainless steel, requiring higher cutting forces and resulting in quicker tool wear. Here are key guidelines for effective machining: A) Utilize a powerful, rigid machine with a strong tool and workpiece mount; B) Keep tool extensions minimal to reduce vibration; C) Maintain a short tool nose radius to ensure the carbide edge remains sharp yet strong; D) Sequence machining so that each cut's depth is below the work-hardened layer from prior operations.
