Duplex Steel Tube:


Due to the characteristics of the two-phase organization, the duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel by properly controlling the chemical composition and heat-treatment process.


It combines the excellent toughness and weldability of austenitic stainless steel with the higher strength and chloride stress corrosion resistance of ferritic stainless steel, and it is these superior properties that make duplex stainless steel develop rapidly as a weldable structural material
