Duplex Steel 2205 Seamless Pipes Useful info

Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. The S31803 grade stainless steel has undergone a number of modifications resulting in UNS S32205, and was endorsed in the year 1996. This grade offers higher resistance to corrosion.

Alloy UNS Description
2205/2205D S31803/S32205 Duplex 2205/2205D is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.
2205 S31803 Duplex 2205 is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.
2205D S32205 Duplex 2205D is used in environments where resistance to general corrosion and chloride stress corrosion cracking is important.

Piyush Steel is mahnufacturers, stockiest & suppliers of Duplex Stainless Steel Pipes. Duplex Stainless Steel Pipes have special quality finishing and duress for long life, high pressure and zero defects.

Our duplex innovation is unmatched in the industry and our offering covers a full palette of duplex stainless steels for use in diverse industries and applications.  The duplex grades LDX 2101® and 2304 are referred to as lean duplex grades. Typical applications are storage tanks, bridges, water heaters and reinforcement bars. The corrosion resistance is comparable to the standard austenitic grades like 4301 and 4404 respectively or high alloyed ferritics like 4521. Grades 2507 and 4501 are regarded as super duplex grades. They are highly alloyed and have a corrosion resistance comparable to high performance austenitics like 254 SMO®. Typical applications for super duplex are desalination plants, seawater systems, flue-gas cleaning, umbilicals, storage tanks and pressure vessels.

Applications

Some of the typical applications of duplex steel grade 2205 are listed below:

  • Oil and gas exploration
  • Processing equipment
  • Transport, storage and chemical processing
  • High chloride and marine environments
  • Paper machines, liquor tanks, pulp and paper digesters

Weldability

Duplex stainless steels generally have good weldability and can be welded using most of the welding methods used for austenitic stainless steels:

  • Shielded metal arc welding (SMAW)
  • Gas tungsten arc welding TIG (GTAW)
  • Gas metal arc welding MIG (GMAW)
  • Flux-cored arc welding (FCW)
  • Plasma arc welding (PAW)
  • Submerged arc welding (SAW)
  • Laser welding
  • Resistance welding
  • High-frequence welding

Corrosion resistance

Duplex stainless steel grades are superior to standard austenitics with regard to stress corrosion cracking resistance, and duplex grades are also good in a number of acidic and alkaline environments.
