2205 Duplex Stainless Steel Good For:
2205 duplex stainless steel has the ability to resist chloride environment and sulfide stress corrosion, and its strength is about twice that of standard austenitic stainless steel. When higher mechanical strength/lighter weight is required, this alloy can be successfully used as a substitute for 300 series austenitic stainless steel.
The yield strength of 2205 duplex stainless steel is more than double that of ordinary austenitic stainless steel, a feature that allows designers to reduce weight when designing products, making this alloy more affordable than 316 and 317L. This alloy is particularly suitable for use in the -50°F/+600°F temperature range. For applications outside this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.
Due to the chromium content (22%), molybdenum (3%) and nitrogen content (0.18%), the corrosion resistance of 2205 is better than 316L and 317L in most environments.
