Product Description

Large Size 133*3mm 2205 2507 600G Duplex Stainless Steel Welded Tube


Duplex stainless steel pipe has good weldability. Compared with ferritic stainless steel and austenitic stainless steel, it is neither like the weld heat affected zone of ferritic stainless steel, nor is it sensitive to weld hot crack as austenitic stainless steel because of severe grain coarsening.
Duplex stainless steel is widely used in petrochemical equipment, seawater and wastewater treatment equipment, oil pipeline, paper machinery and other industrial fields because of its special advantages. In recent years, duplex stainless steel has also been studied and applied in the field of bridge load-bearing structure, which has good prospects for development.
Duplex stainless steel consists of ferrite phase and austenite phase in its quenched structure, and the content of the minimum phase may reach 30%.

Duplex 2205 2507 Stainless Steel


The main alloying elements of duplex steel are Cr, Ni, Mo and N. Among them, Cr and Mo increase ferrite content, while Ni and N are austenite stable elements. Some steels also contain elements such as Mn, Cu and W. Cr, Ni and Mo can improve the corrosion resistance. In the chloride-containing environment, its pitting and crack corrosion resistance is particularly good.
