  • Forms of duplex 2205 available at Huaan international:
    • Sheet
    • Plate
    • Bar
    • Pipe & tube (welded & seamless)
    • Fittings (i.e. flanges, slip-ons, blinds, weld-necks, lap joints, long welding necks, socket welds, elbows, tees, stub-ends, returns, caps, crosses, reducers, and pipe nipples)
    • Welding wire and welding electrode
  • Usages:
    • Usage of 2205 Duplex stainless steel should be limited to temperatures below 600° F. Extended elevated temperature exposure can embrittle 2205 stainless
  • The combination of Cr, Mo and Ni convey the good resistance of 2205 to chloride pitting and crevice corrosion
  • This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications
  • The high chromium, molybdenum and nitrogen contents of 2205 provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environment
  • What are the characteristics of Duplex 2205:
    • High resistance to chloride stress corrosion cracking
    • Resistance to chloride pitting and crevice corrosion
    • Good general corrosion resistance
    • Good sulfide stress corrosion resistance
    • High strength
    • Good weldability and workability
  • In what applications is Duplex 2205 used:
    • Chemical process vessels, piping and heat exchangers
    • Pulp mill digesters, bleach washers, chip pre-steaming vessels
    • Food processing equipment
    • Oil field piping and heat exchangers
    • Flue gas desulfurization equipment
  • Available size range for seamless pipes and tubes:
    • OD: 6-168mm
    • WT: 0.5-15mm
