2205 Duplex Stainless Steel Overview
2205 is a duplex (austenitic-ferritic) stainless steel containing about 40-50% ferrite in the annealed condition. This alloy provides a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless steels. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L stainless in most environments. 2205 is not recommended for operating temperatures above 600°F.
The design strength of 2205 is significantly higher than 316/316L, often permitting lighter wall construction. 2205 has good notch impact toughness down to temperatures below -40°F. 2205 is welded with E2209 or ER2209 fillers.
