Duplex Steel Sheet

High Strength Duplex Steel Sheets, Corrosion Resistant Duplex Plates, ASTM A240 Duplex Steel Sheet & Plate Supplier, Exporter & Stockist in Mumbai, India

Duplex Steel Sheet & Plate are made from a two-phase microstructure consisting of austenitic and ferritic stainless steel. This combination offers superior strength, excellent resistance to stress corrosion cracking, and enhanced toughness when compared to standard stainless steel grades.

These plates exhibit twice the yield strength of conventional austenitic stainless steels and are ideal for aggressive environments involving chlorides and high mechanical stress. Manufactured to ASTM A240 / ASME SA240 standards, Duplex sheets and plates are available in multiple grades like 2205, 2304, 2507, UNS S31803, S32205, etc.
