Super Duplex Stainless Steel Grades

  • 2205
  • 2507

 

2205 (UNS S32760)

2205 is a duplex stainless steel with a micro structure of nearly equal proportions of austenite and ferrite, when properly heat treated. This micro structure ensures that 2205 is much more resistant to stress corrosion cracking than Stainless Steel 304 or 316L. Its higher chromium, molybdenum, and nitrogen content gives the product significantly improved pitting and crevice-corrosion resistance in the presence of chlorides.

Stainless Steel 2205 also has better general corrosion resistance than 316L in most environments. In addition, 2205 has a 0.2% proof stress of approximately double that of conventional austenitic stainless steels. Stainless Steel 2205 is highly suitable for service in environments containing chlorides and hydrogen sulfide, such as marine applications and the oil and gas extraction and processing industries.

Common Applications of 2205 Duplex Stainless Steel

  • Chemical industry (processing, transport and storage, pressure vessels, tanks, and piping)
  • Pulp and paper industry (digesters and liquor tanks)
  • Mining industry
  • Heat exchangers (especially those where chloride-bearing water or brackish water is used as the cooling medium)
  • Production tubing and flow lines for the extraction of oil and gas from sour wells

 

2507(UNS S32750)

2507 is a super duplex stainless steel designed for demanding applications, such as chemical processing, petrochemical plants, and seawater equipment, which require exceptional strength and corrosion resistance. The product has excellent resistance to chloride stress, corrosion, and high thermal conductivity, with a low coefficient of thermal expansion. The high chromium, molybdenum, and nitrogen levels provide excellent resistance to pitting, crevice, and general corrosion. The impact strength is also high, and weldability is good.

 

  • Good resistance to uniform pitting, and crevice corrosion
  • Heat resistance to stress-corrosion cracking and corrosion fatigue
  • High mechanical strength
  • Good abrasion and erosion resistance
  • Good weldability

 

Common Applications of 2507 Super Duplex Stainless Steel

  • Oil and gas industry equipment
  • Storage tanks, pressure vessels
  • Heat exchangers
  • Rotors, impellers, and shafts
  • Cargo tanks and pipe system in chemical tankers
  • Pulp and paper industry
  • Desalination plants
  • Flue-gas cleaning
  • Seawater systems
  • Bridges
  • Water heaters
