2205 Duplex Stainless Steel Round Tube for Marine and Chemical Processing Applications

Product Introduction

2205 Duplex Stainless Steel Round Tube is a high-strength corrosion-resistant tubing material designed for demanding marine, chemical and industrial environments. Made from Duplex 2205 / UNS S32205 or S31803, it combines the advantages of austenitic and ferritic stainless steels, offering high mechanical strength together with excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.

Our 2205 Duplex Stainless Steel Round Tube for Marine and Chemical Processing Applications is available in different outside diameters, wall thicknesses, lengths and surface conditions. Customized cutting, polishing and fabrication services are available according to customer drawings and project requirements.

Product Specifications
