2205 is a duplex (austenitic-ferritic) stainless steel containing about 40 - 50% ferrite 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 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.


Features

  • 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

Applications

  • Chemical process vessels, piping, and heat exchangers
  • FGD scrubber systems
  • Pulp mill digesters, bleach washers, chip presteaming vessels
  • Food process equipment
  • Oil field piping, heat exchangers
