Known for their superior strength, excellent corrosion resistance, and cost-efficiency, these pipes and tubes offer a long-term solution where both mechanical performance and durability are critical.

Let’s take a closer look at what makes Duplex S32205 such a powerful material, and why it’s a smart option for a wide range of applications.

What is Duplex Steel S32205?
Duplex S32205, also referred to as UNS S32205 or DIN 1.4462, is a nitrogen-enhanced duplex stainless steel. What sets it apart is its balanced microstructure, made up of approximately 50% austenite and 50% ferrite. This combination delivers the best of both worlds—high strength from ferritic steel and excellent corrosion resistance from austenitic steel.

Key Benefits of Duplex Steel S32205 Pipes & Tubes
1. High Strength
S32205 offers nearly twice the yield strength of standard austenitic stainless steels like 304 and 316. This allows for the use of thinner wall thicknesses without compromising pressure performance, resulting in weight savings and lower material costs.

2. Excellent Corrosion Resistance
With ...
... higher levels of chromium (22%), molybdenum (3%), and nitrogen, Duplex S32205 performs exceptionally well in:

Chloride-rich environments

Acidic and alkaline conditions

Offshore and marine applications It resists pitting, crevice corrosion, and stress corrosion cracking more effectively than many other stainless steels.

3. Outstanding Durability
Designed to operate in the harshest environments, S32205 pipes and tubes handle high pressures, extreme temperatures, and chemically aggressive media without degradation.

4. Good Weldability & Fabrication
Despite its high strength, Duplex S32205 maintains good weldability and can be fabricated using standard methods—making it easier to install and maintain in complex piping systems.

Applications of Duplex Steel S32205 Pipes & Tubes
These pipes and tubes are ideal for industries that demand high-performance, corrosion-resistant piping. Typical applications include:

Oil & Gas Pipelines

Offshore Drilling Platforms

Heat Exchangers

Desalination Plants

Chemical Processing Equipment

Marine & Shipbuilding

Pulp and Paper Industry

Forms and Standards
Duplex Steel S32205 Pipes & Tubes are available in various forms:

Seamless and welded pipes
