Duplex 2205 Round Bar is a highly versatile duplex ferritic-austenitic stainless steel bar, boasting an impressive 22% chromium, 3% molybdenum, and 5-6% nickel content. This exceptional alloy is widely recognized as the most commonly used duplex stainless steel grade. It stands out with twice the yield strength of conventional austenitic grades and superior fatigue strength. Furthermore, Duplex 2205 offers outstanding resistance to stress corrosion cracking, crevice corrosion, pitting, erosion, and general corrosion, even in the harshest environments.
Leading producers recommend a maximum hot forming temperature range for Duplex 2205 between 2010 and 2100°F (1100 to 1150°C). If the workpiece is not compact, its edges may cool faster than the bulk, increasing the risk of cracking in the cooler regions.
The Duplex 2205 stainless steel is renowned for its excellent formability across a wide range of fabrications. However, its remarkable high strength can present certain challenges during processing. Even when the equipment is adequately powered, it's essential to account for the increased spring-back due to the grade's robust strength. Plan accordingly to ensure superior results.
The Duplex stainless steel bar 2205 presents a slight challenge compared to the 300 series austenitic stainless steel in terms of machinability. It demands higher cutting forces, leading to quicker tool wear. To achieve optimal machining results, follow these guidelines: A) Use a powerful, rigid machine with a very strong tool and workpiece mount; B) Maintain short tool extensions to reduce vibration; C) Ensure the tool nose radius isn't unnecessarily long to keep the carbide edge sharp yet strong; D) Sequence the machining process so the depth of cut consistently remains beneath the work-hardened layer from the prior operation.
