Duplex steel welded tubing is crafted from duplex stainless steel, which strikes a perfect balance between the strength of ferritic stainless steel and the corrosion resistance of austenitic stainless steel. Thanks to its welded construction, this tubing can be produced cost-effectively in longer lengths while still maintaining excellent mechanical properties and structural integrity. It boasts outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides and other aggressive substances. Additionally, it offers high tensile and yield strength, good toughness, and dependable weldability for demanding applications.
