Mechanical Properties of Duplex Steel 2205 Tubing

The table provides essential information for engineers and manufacturers to assess the integrity and durability of the Duplex Steel 2205 Tubing in demanding environments.

Thus, this valuable data on the strength, flexibility, and resilience of the Duplex Steel 2205 Tubing is crucial for ensuring reliability and longevity.

Advantages of Duplex Steel 2205 Tubing

These flexible Forged Fittings offer numerous benefits for various industrial applications.

•  High Strength: It has a yield strength of about two times the standard austenitic stainless steel, like 304 and 316. This high strength enables the use of thinner tubing walls without affecting the structural strength.
• Superior Corrosion Resistance: It also has good resistance to pitting, crevice corrosion and stress corrosion cracking, especially in chloride-containing solutions. This makes Duplex 2205 tubing well-suited for severe and aggressive environments.
• Good Toughness and Ductility: Duplex 2205 has satisfactory toughness and flexibility even at low temperatures, making it suitable for use under various operating conditions.
• Excellent Weldability: Duplex 2205 can be welded using conventional techniques without the danger of sensitisation that results in intergranular corrosion.
• Enhanced Fatigue Resistance: The material has a duplex structure, and therefore, it offers better fatigue properties, which are essential in applications where the material is subjected to cyclic loading.

Duplex Steel 2205 Tubing offers several advantages that make it suitable for industrial and commercial applications.

Common Applications of Duplex Steel 2205 Tubing

Due to its excellent features, the Duplex Steel 2205 Tubing is preferred in various industrial applications. Some of the main applications include.

• Chemical Processing: Tubing is most suitable for use in chemical processing industries, where it is used in reactors, piping systems, and heat exchangers that are in contact with aggressive chemicals and high temperatures.
• Marine Applications: It is used in marine applications since it does not rust when exposed to seawater; it is used in shipbuilding, desalination plants, and other marine structures.
• Pulp and Paper Industry: In the pulp and paper industry, the application of Duplex 2205 tubing is in the bleach plants and other areas where chemicals cause corrosion; this makes the tubing last longer and require minimal replacement.
• Power Generation: Due to its high strength, corrosion, and high-temperature resistance, it is used in power generation appliances like boilers, condensers, and heat exchangers.
• Water Treatment: The tubing made from Duplex 2205 is used for pumps, valves, and filtration equipment in water treatment facilities because of its ability to resist corrosion and last longer.
• Pharmaceutical Industry: In the pharmaceutical industry, the tubing is employed in processing equipment, which must not be contaminated by chemicals and, at the same time, should not corrode from the chemicals.
• Architectural Applications: It is also applied in architectural constructions where strength, durability and beauty are considered, such as structures and handrails.

Duplex Steel 2205 Tubing is applied across various industries due to its valuable features, which make it versatile.
