Product Description

Seamless and Welded 2205 1.4362 Duplex Stainless Steel Pipe / Tube


Wuxi Sino Yuan Science and Technology Co.,Ltd is one of the toppest 2205,2205 stainless steel pipe , China steel supplier in China.During these years of exporting , Wuxi Sino Yuan Science and Technology Co.,Ltd now has rich .


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 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.

Duplex 2205 Stainless Steel Pipe


Standard: ASTM A240/A240M--01 chromium 2205 duplex stainless steel alloy is a 22%, 2.5% 4.5%-NI-n alloy composition Mo and duplex stainless steels. It has high strength, good toughness and good global and local resistance to stress corrosion.


Heat treatment performance:


2205 alloy should be annealed at the lowest temperature of 1900º F, then cooled rapidly and quenched by water. This treatment is applied to solid melting annealing and stress relief. Stress relief treatment, if carried out at temperatures below 1900º F, can easily lead to the precipitation of harmful metal or non-metal phases.
