Corrosion Resitance
1. Due to its high chromium, molybdenum, and nitrogen content,
Duplex 2205 demonstrates superior corrosion resistant properties to
316 and 316L in most environments
2. Chromium, molybdenum, and nitrogen content also provide high
resistance to pitting and crevice corrosion, even in oxidizing and
acidic solutions
3. Resistant to chloride stress corrosion cracking and temperatures
of up to about 302°F (150°C)
4. The presence of ferrite provides for good performance of Duplex
2205 in caustic environments
Heat Resitance
1. Similar to other duplex stainless steels, Duplex 2205 has good
oxidation resistance at high temperatures
2. Subject to embrittlement when exposed to temperatures above
572°F (300°C) even when exposed for short periods of time; Duplex
2205 is therefore not recommended for use above 572°F (300°C)
Machinability
Duplex 2205 is somewhat more difficult to machine than the 300
series austenitic stainless steels. Higher cutting forces are
required and more rapid tool wear is typical. Some guidelines for
machining are: A) Use powerful, rigid machines with extremely
strong rigid mounting of tools and work piece, B) Minimize
vibration by keeping the tool extension as short as possible, C)
Use a nose radius on the tool, no longer than necessary, for
carbides that have a sharp edge while still providing adequate
strength, D) Design machining sequences to always provide for a
depth of cut below the work hardened layer resulting from the
previous passes
