产品说明
Alloy 2205 is a 22% Chromium, 3% Molybdenum, 5-6% Nickel, nitrogen alloyed duplex stainless steel with high general, localized and stress corrosion resistance properties in addition to high strength and excellent impact toughness.

Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in almost all corrosive media. It also has high corrosion and erosion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.

The yield strength is about twice that of austenitic stainless steels. This allows a designer to save weight and makes the alloy more cost competitive when compared to 316L or 317L.

Alloy 2205 is particularly suitable for applications covering the -50°F/+600°F temperature range. Temperatures outside this range may be considered but need some restrictions, particularly for welded structures.

Applications
  • Pressure vessels, tanks, piping, and heat exchangers in the chemcal processing industry
  • Piping, tubing, and heat exchangers for the handling of gas and oil
  • Effluent scrubbing systems
  • Pulp and paper industry digesters, bleaching equipment, and stock-handling systems
  • Rotors, fans, shafts, and press rolls requiring combined strength and corrosion resistance
  • Cargo tanks for ships and trucks
  • Food processing equipment
  • Biofuels plants
