  • Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.

    APPLICATION OF DUPLEX 2205 STAINLESS STEEL SHEET/PLATE:

    • Chemical processing transport and storage - pressure vessels, tanks, and heat exchangers
    • Oil and gas exploration and processing equipment - piping, tubing, and heat exchangers
    • Marine and other high chloride environments
    • Effluent scrubbing systems
    • Pulp and paper industry - digesters, bleaching equipment, and stock-handling systems
    • Cargo tanks for ships and trucks
    • Food processing equipment
    • Biofuels plants
  • ADDITIONAL PROPERTIES OF DUPLEX 2205 STAINLESS STEEL SHEET/PLATE

    • Corrosion Resistance
      >>Due to its high chromium, molybdenum, and nitrogen content, Duplex 2205 demonstrates superior corrosion resistant properties to 316 and 316L in most environments
      >>Chromium, molybdenum, and nitrogen content also provide high resistance to pitting and crevice corrosion, even in oxidizing and acidic solutions
      >>Resistant to chloride stress corrosion cracking and temperatures of up to about 302°F (150°C)
      >>The presence of ferrite provides for good performance of Duplex 2205 in caustic environments
    • Heat Resistance
      >>Similar to other duplex stainless steels, Duplex 2205 has good oxidation resistance at high temperatures
      >>Subject to embrittlement when exposed to temperatures above 572°F (300°C) even when exposed for short periods of time; Duplex 2205 is therefore not recommended for use above 572°F (300°C)
  • SURFACE FINISH OF DUPLEX 2205 STAINLESS STEEL SHEET/PLATE :

    *Not all finishes are available in all alloys - (contact Yieh United Sales for more information)

    #1 Finish Hot rolled, annealed and pickled.
    #2D Finish A uniform, dull silver gray mill finish that is applied to thinner stainless steel coils,the thickness of which has been reduced by cold rolling.
    #2B Finish A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
    #3 Finish A semi polished surface achieved by finishing with the equivalent of a 80 to 120 grit abrasive. This finish has a pronounced grit line.
    #4 Finish Also called brushed, directional or satin finish. A is characterized by fine polishing grit lines that are uniform and directional in appearance. The final abrasive used in the process is 150 to 220 grit.
    #4 Satin Brush Finish 150 to 180 grit finish A fine directional polish, typically used in the washroom accessories industry. Most 3.5″ floppy diskette cover plates have this finish.
    #6 Finish Polished finish achieved with the equivalent of a 240 grit abrasive. Finer grit lines and higher reflectivity than a No. 4 finish.
    #7 Finish Highly reflective surface obtained with the equivalent of a 320 grit abrasive. Minimal grit lines.
    No. 8 or True #8 mirror This is the most reflective mirror finish on the market. All of the polishing, or “grit,” lines from the preliminary polishing operations are removed. The look is that of a glass mirror. Sometimes referred to as a non directional mirror finish, Super 8, No. 9, Perfect No. 10, and even No. 12 mirror.
    CMP Super #8 mirror Chemical Mechanical Polished Super #8 mirror finished sheets are guaranteed to be free from any manufacturing defects. This product represents the ultimate in mirror polished stainless steel. It is available as a single-sided or double-sided mirror polished sheet.
    Hairline finish 80 – 140 grit finish A well defined directional polish. Starting base substrate is a No. 4 finish sheet; these sheets are polished to provide a “continuous long grain” hairline look. A finish which is popular with architects for its aesthetic, it is equally popular with fabricators due to it’s ease of fabrication and finish matching properties after welding operations.
