Duplex Steel 2205 Sheets | UNS S31803 Sheets Supplier.
When strength, corrosion resistance, and cost efficiency are critical, Duplex Steel 2205 Sheets emerge as a reliable and versatile material choice. As a trusted UNS S31803 Sheets Supplier, we offer high-quality sheets manufactured to meet stringent international standards, serving a wide range of industrial applications across global markets.
What is Duplex Steel 2205 (UNS S31803)?
UNS S31803, commonly known as Duplex Steel 2205, is a nitrogen-enhanced duplex stainless steel with a balanced austenitic-ferritic microstructure. This unique composition delivers excellent mechanical strength, superior resistance to stress corrosion cracking, and outstanding performance in chloride-rich environments.
Manufactured as per ASTM A240 / ASME SA240, Duplex Steel 2205 Sheets provide better corrosion resistance and nearly twice the yield strength of standard austenitic stainless steels like 304 and 316.
Key Features of Duplex Steel 2205 Sheets
High resistance to pitting and crevice corrosion
Excellent performance against stress corrosion cracking
Superior strength with reduced material thickness
Good weldability and formability
Long service life with low maintenance cost
