High-performance 2205 stainless steel tube with excellent corrosion resistance and high strength. Available in seamless or welded types. China’s leading manufacturer with full customization and global certifications.
China’s Leading Stainless Steel Tube Manufacturer
At Jiuguang Metal, we manufacture and export premium 2205 duplex stainless steel tubes, engineered for demanding applications that require both high strength and excellent corrosion resistance. 2205 is the most widely used duplex grade, featuring a balanced austenitic-ferritic structure that provides superior stress corrosion cracking resistance, twice the yield strength of 304/316, and excellent weldability.
Whether you’re in the chemical industry, marine environments, offshore oil & gas, or pressure vessel applications, our factory can deliver custom-cut 2205 tubes with strict dimensional tolerances, certified to ASTM, AISI, EN, JIS, and DIN standards. Full OEM customization is available, backed by EN10204 3.1/3.2 documentation.
