S31803 steel is ultra-low carbon dual- phase stainless acid resistant steel. It is provided with excellent pitting corrosion and crevice corrosion resistant performances. In addition, nitrogen, as a strong element that forms and stabilizes austenite, still ensures the existence of certain amount of austenite in the structure even if after welding or heating under high temperature, and makes it difficult to form single-phase ferrite. The dual-phase proportion is not sensitive to the change of heating temperature.

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
