EN 10216-5 1.4462 / Duplex 2205 Stainless Steel Seamless Pipe Annealed & Pickled
EN 10216-5 is a part of the EN 10216 standard that specifically
deals with seamless stainless steel tubes for pressure purposes.
The specific alloy you mentioned, 1.4462 (also known as UNS S32205
or SAF Duplex 2205), is a duplex stainless steel known for its high
strength and strength and excellent corrosion resistance, making it
highly effective in demanding industrial environments.

Corrosion Resistance
- Pitting Corrosion: Has a high pitting resistance equivalent number (PREN), typically around 40. This makes it suitable for use in aggressive environments, such as those containing chlorides.
- Stress Corrosion Cracking (SCC): Better resistance to SCC compared to conventional austenitic stainless steels, making it a preferred choice in chloride-rich environments.
- General Corrosion: Excellent resistance to general corrosion in a variety of environments, including acids.
Testing and Standards
- Non-Destructive Testing (NDT): Pipes are often subjected to NDT methods (like ultrasonic testing) to ensure integrity and detect any internal flaws.
- Dimensional and Mechanical Tests: Encompasses tests for tensile strength, yield strength, elongation, and hardness as per the standard requirements.
- Hydrostatic Testing: Each pipe may also undergo hydrostatic testing to ensure it can withstand pressure without leaking.
Fabrication and Forming
- Welding:
- Suitable for welding using most conventional methods (TIG, MIG, etc.).
- It is recommended to use filler materials that match the composition of the base metal to ensure corrosion resistance and mechanical properties.
- Post-weld heat treatment (PWHT) is not typically required, but it should be controlled to prevent overheating.
- Cold Working: Duplex steels can be cold worked, but this should be done carefully to avoid work hardening, which can lead to reduced ductility.

Applications
- Oil and Gas Industry: Used in pipelines, fittings, and components for offshore and subsea applications due to its high strength and corrosion resistance.
- Chemical Processing: Ideal for processes involving aggressive chemicals, particularly in environments where chlorides are present.
- Marine Applications: Frequently used in hulls, vessels, and other marine structures exposed to seawater.
- Heat Exchangers: Suitable for heat exchangers in both seawater and industrial applications.
