UNS S32304 / 2304 / DIN 1.4362 Duplex Steel Pipes & Tubes in Spain: A Rising Standard in Industrial Piping Solutions

 Spain’s diverse industrial sectors—including petrochemical, desalination, construction, and renewable energy—demand durable, high-performance materials capable of withstanding harsh conditions without compromising on cost-efficiency. One alloy gaining prominence in these sectors is UNS S32304 / 2304 / DIN 1.4362 Duplex Stainless Steel Pipes & Tubes in Spain. Known for its superior strength, corrosion resistance, and affordability, this duplex steel grade is increasingly preferred for pipes and tubes across Spain.

Leading the way in supplying high-quality duplex steel products in the Spanish market is Vento Tubos, a trusted name in stainless and duplex steel piping solutions.

What is UNS S32304 / 2304 / DIN 1.4362?

UNS S32304, also known as Alloy 2304 or DIN 1.4362, is a lean duplex stainless steel with a balanced microstructure of ferrite and austenite. This unique composition offers exceptional mechanical strength—roughly twice that of standard austenitic steels—along with excellent resistance to corrosion, especially in chloride-rich environments.

Key Properties:

  • High Strength: Around double the yield strength of 304/316 steels
  • Superior Corrosion Resistance: Effective in brackish, saline, and chemical environments
  • Weldability: Good performance with low risk of intergranular corrosion
  • Cost-Effective: Reduced content of expensive alloying elements like nickel and molybdenum

Applications of UNS S32304 / 2304 / DIN 1.4362 duplex steel pipes and tubes

The use of UNS S32304 / 2304 / DIN 1.4362 duplex steel pipes and tubes is growing rapidly across various sectors in Spain:

1. Desalination and Water Treatment

With Spain’s significant investment in desalination technologies, especially in arid regions and coastal cities, duplex steel is essential for handling saline water. Vento Tubos supplies corrosion-resistant duplex steel piping for seawater reverse osmosis (SWRO) plants and related infrastructure.

2. Oil & Gas and Petrochemical

In offshore and onshore facilities, the material’s resistance to stress corrosion cracking and high mechanical strength make it ideal for pipelines and pressure systems. Vento Tubos provides duplex steel tubing solutions compliant with stringent international standards for hydrocarbon processing.

3. Construction and Infrastructure

In architectural and civil engineering projects, especially in marine environments such as the ports of Bilbao and Málaga, duplex steel from Vento Tubos offers long-term durability and aesthetic appeal for exposed structural elements.

4. Renewable Energy

As Spain accelerates its transition to green energy, 2304 duplex steel is playing a role in wind and solar thermal power systems. Its fatigue resistance and strength-to-weight ratio are ideal for turbine towers, support frames, and hydraulic piping.
