Bangles 2205 Stainless Round Bar

We export and supply 2205 Stainless Round Bar to our clients in Wuxi, Jiangsu, China. 2205 is the most widely used duplex (ferritic/austenitic) stainless steel grade. It finds applications due to both excellent corrosion resistance and high strength. The standard S31803 composition has over the years been refined by many steel suppliers, and the resulting restricted composition range was endorsed as UNS S32205 in 1996. S32205 gives better guaranteed corrosion resistance, but much of the S31803 currently produced also complies with S32205.
Processing
The high strength that makes 2205 useful in many applications also reduces its mach inability. The high work-hardening rate further decreases the machinability of 2205. Cutting speeds are approximately 20% slower than for a standard grade 304. The high strength of 2205 also makes bending and forming more difficult; these operations will require larger capacity equipment than would be required for austenitic stainless steels. The ductility of 2205 is less than that of an austenitic grade (but is not low when compared to most other structural materials), so severe forming operations, such as cold heading, are not generally possible. If severe cold working is required it is recommended that intermediate annealing be carried out.
