The EN 10216-5 UNS S32205 seamless tube is a duplex stainless steel tube with excellent mechanical properties and corrosion resistance. It is widely used in applications requiring high strength and excellent resistance to stress corrosion cracking and pitting. This tube conforms to the EN 10216-5 European standard for seamless steel tubes and uses the UNS S32205 (commonly referred to as Duplex 2205) material grade.
Key Features
Material Composition: UNS S32205 is a duplex stainless steel with a balanced mixture of austenite and ferrite phases, providing superior strength and corrosion resistance.
Chemical composition:
Chromium (Cr): 22–23%
Nickel (Ni): 4.5–6.5%
Molybdenum (Mo): 3.0–3.5%
Nitrogen (N): 0.14–0.2%
Low carbon content ensures excellent weldability and reduces the risk of intergranular corrosion.
Corrosion Resistance:
Exceptional resistance to chloride-induced pitting and crevice corrosion.
High resistance to stress corrosion cracking (SCC), especially in environments with high chloride concentrations.
Mechanical Properties:
High yield strength and tensile strength compared to austenitic stainless steels.
Good ductility and toughness, even in low-temperature environments.
Compliance:
Fully meets the requirements of the EN 10216-5 standard for seamless stainless steel tubes.
Manufactured with precision to ensure dimensional accuracy and surface quality.
Applications
The EN 10216-5 UNS S32205 seamless tube is used in a variety of industries due to its combination of strength, corrosion resistance, and durability. Common applications include:
Oil & Gas Industry: For pipelines, heat exchangers, and offshore platforms.
Chemical Processing: For handling corrosive chemicals and high-pressure systems.
Marine Engineering: For seawater systems and desalination plants.
Pulp & Paper Industry: For equipment exposed to aggressive bleaching agents.
Power Generation: For high-pressure steam systems and heat recovery systems.
Benefits
Durability: Long service life even in harsh environments.
Cost-Effective: Combines the benefits of austenitic and ferritic alloys, reducing material costs.
Versatility: Suitable for both structural and pressure-bearing applications.
Standards and Specifications
Standard: EN 10216-5
Grade: UNS S32205 / Duplex 2205
Form: Seamless tube
Dimensions: Customized per client requirements (outer diameter, wall thickness, and length).
