What is UNS S31803 Duplex Pipe?
UNS S31803 duplex pipe is a stainless steel pipe made from duplex grade material that contains a balanced microstructure of austenite and ferrite. It offers high strength, excellent resistance to corrosion, stress corrosion cracking, and pitting, making it ideal for harsh industrial environments such as offshore, chemical processing, and marine applications.

What is Duplex Steel UNS S31803 Pipe?

Duplex Steel UNS S31803 Pipe, also known as Duplex Steel 1.4462 Pipe, is a widely used duplex stainless steel grade that provides a combination of austenitic and ferritic properties. This dual-phase structure results in:

• Higher strength than standard stainless steels
• Superior resistance to chloride stress corrosion cracking
• Excellent resistance to pitting and crevice corrosion
• Enhanced durability in aggressive environments

We manufacture and supply ASME SA790 Duplex Stainless Steel S31803 Pipes that meet stringent quality and performance benchmarks, ensuring reliability in the most demanding conditions.
