China STUB END Manufacturer Yaang offers ASME B16.9 ASTM A815 F51 Welded Lap Joint Stub End, 14 Inch, Schedule STD.

UNS S31803 and UNS S32205 are commonly referred to as Duplex 2205 material, whose “Duplex” name is derived from the mixed microstructure which contains about equal portions of ferrite and austenite. Developed more than 70 years ago in Sweden precisely for the sulfite paper industry where the Duplex’s were used to combat corrosion problems caused by chloride-bearing cooling waters and other aggressive chemical products. Since then there have been advancements in the composition such as the deliberate addition of nitrogen as an alloying agent, which afterwards quickly made Duplex the “workhorse” of stainless steels.

Generally, UNS S31803 has been solely designated to the Duplex 2205 grade. More recently, it has been available complying with the higher corrosion resistant composition UNS S32205. The only difference in the UNS numbers is that UNS S32205 contains a higher nitrogen content which guarantees better corrosion resistance. Composed of between 21% to 23% chromium, 4.5% to 6.5% nickel, 5% to 3.5% molybdenum, 2% manganese, and 1% silicon, with the balance being iron. Also found in Duplex Stainless Steel are trace amounts of carbon, phosphorus, sulfur and nitrogen.

Benefits of Duplex include: good weldability and workability, high resistance to corrosion fatigue, stress corrosion cracking (especially chloride stress corrosion cracking), erosion, and high energy absorption. Other advantages of Duplex are higher heat conductivity and low thermal expansion compared to austenitic stainless steels, high strength, good resistance to sulfide stress corrosion, and high resistance to pitting and crevice to corrosion. Duplex 2205® accounts for over 80% of the total usage of Duplex stainless steels throughout the world because of its superior workability as well as corrosion resistance.

Welding Characteristics:

  • Possesses good weldability
  • Should not generally be welded without filler metal as this may result in excessive ferrite

Heat Treatment:

  • Annealing temperature range is 1868 to 2012°F (1020 to 1100°C)
  • Cannot be hardened by heat treatment – but Duplex 2205 does work-harden
  • Special consideration is needed to compensate for a higher coefficient of thermal expansion to avoid warping and distortion

Processing – Hot Forming:

Most Duplex 2205 producers recommend a maximum hot forming temperature between 2010 and 2100°F (1100 to 1150°C). If the shape of the work piece is not compact, the edges may be significantly cooler than the bulk, and there is risk of cracking in the cooler regions.

Processing – Cold Forming:

Duplex 2205 has shown good formability in a variety of fabrications. The high strength of Duplex 2205 can pose problems. Even when the equipment has sufficient power, allowance must be made for higher spring-back caused by the grade’s high strength.

Machinability:

Duplex 2205 is somewhat more difficult to machine than the 300 series austenitic stainless steels. Higher cutting forces are required and more rapid tool wear is typical. Some guidelines for machining are: A) Use powerful, rigid machines with extremely strong rigid mounting of tools and work piece, B) Minimize vibration by keeping the tool extension as short as possible, C) Use a nose radius on the tool, no longer than necessary, for carbides that have a sharp edge while still providing adequate strength, D) Design machining sequences to always provide for a depth of cut below the work hardened layer resulting from the previous passes.

Applications:

  • Chemical processing, transport and storage – pressure vessels, tanks, piping, 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

Standards:

  • ASTM/ASME: A240 UNS S32205/S31803
  • EURONORM: 1.4462 X2CrNiMoN 22.5.3
  • AFNOR: Z3 CrNi 22.05 AZ
  • DIN: W.Nr 1.4462
