ASME SA789 Stainless steel duplex steel 2205 welded pipe UNS S31803, UNS 32205

 

2205 is a Duplex Stainless combination of Ferritic & Austenitic. It has higher corrosion resistance than 316 (3% min. Moly vs 2% in 316) Duplex 2205 is highly resistant to stress corrosion & Chloride cracking. Duplex 2205 is cost effective because it has only 5% Nickel. Duplex stainless has high strength, ductility, toughness and weldability.

 

We offer Stainless steel supplies and stainless steel supply items for all stainless steel tube sizes. We are leading stainless steel tube suppliers, stainless steel tubing suppliers.

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.

 

 

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
