2205
2205 is a duplex (austenitic-ferritic) stainless steel containing approxiamtely 50% ferrite and 50% aystenite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317/317L stainless in most environments. 2205 is not suggested 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.
- High resistance to chloride stress corrosion cracking
- Chloride pitting and crevice corrosion resistance superior to 317L stainless
- Good general corrosion resistance
- High strength
- Good sulfide stress corrosion resistance
- Useful up to 600°F
