Duplex 2205 Round Bar is a high-performance duplex ferritic-austenitic stainless steel, meticulously engineered with 22% chromium, 3% molybdenum, and 5-6% nickel. As the most prevalent grade in duplex stainless steel, it delivers unparalleled yield strength, doubling that of standard austenitic grades. This material excels in fatigue strength and provides exceptional resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion, even in the harshest environments.
Most producers suggest a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). For non-compact shapes, edges may cool faster than the bulk, increasing the risk of cracking in cooler regions.
Duplex 2205 steel exhibits remarkable formability across numerous fabrication processes. However, its exceptional strength presents certain challenges. Even with powerful equipment, it's essential to consider the higher spring-back effect due to the grade's elevated strength.
Machining Duplex stainless steel bar 2205 is somewhat more complex compared to 300 series austenitic stainless steel. The process demands higher cutting forces resulting in quicker tool wear. Here are crucial machining guidelines: A) Utilize a robust, rigid machine with a sturdy tool and workpiece mount; B) Minimize tool extensions to reduce vibration; C) Ensure the tool nose radius is as short as possible to maintain a sharp carbide edge while ensuring adequate strength; D) Plan the machining sequence so that the depth of cut consistently remains below the work-hardened layer from prior operations.
