The Duplex 2205 Round Bar, a duplex ferritic-austenitic stainless steel, is equipped with 22% chromium, 3% molybdenum, and 5-6% nickel, making it the most popular duplex stainless steel grade. Its yield strength is double that of standard austenitic grades, and it boasts exceptional fatigue strength. Duplex 2205 excels in resisting stress corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion, even in the harshest environments.
Manufacturers suggest a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). When the workpiece isn't compact, cooler edges may lead to cracking.
Duplex 2205 exhibits good formability in various fabrications. However, its high strength can pose challenges. Consideration for higher spring-back due to its strength is necessary, even if equipment power is sufficient.
Duplex stainless steel bar 2205 presents a unique machining challenge compared to the 300 series austenitic stainless steel due to its toughness. The increased cutting forces lead to quicker tool wear. Below are some essential machining guidelines to enhance efficiency: A) Employ a robust, rigid machine coupled with a durable tool and workpiece mount; B) Minimize tool extensions to reduce vibration; C) Maintain a minimal tool nose radius to ensure the carbide retains a sharp edge while providing necessary strength; D) Strategically design the machining sequence to ensure the depth of cut consistently remains below the work-hardened layer from any preceding operations.
