Product Description

ASTM A790 Ferritic or Austenitic Stainless Steel Welded Tubes or Seamless tubes for general corrosion service


Size range:
O.D.: 4.0-230mm W.T.:1-30mm L: according to customer requirement

 

Material and Manufacture:

S31200, S31260, S31500, S31803, S32003, S32101, S32202,S32205, S32304, S32506, S32520...

 

Tubes are made from Flat-rolled steel by automatic welding process.

Subsequent to welding and prior to final heat treatment, the tubes are cold drawn or cold rolled

 

Duplex stainless steel:

Duplex stainless steel (DSS), refers to the Ferrite and Austenite each accounted for about 50%, generally less of it also needs to reach 30% of stainless steel. When the Carbon content is low, Cr content is in 18%~28% and Ni content is in 3%~10%. Some steel also contain alloy elements such as Mo, Cu, Nb, Ti, N and so on.

This kind of steel has the characteristics of Austenite and Ferritic, compared with ferrite, it has higher plasticity and toughness, and the no room temperature brittleness, intergranular corrosion resistance and welding performance are improved significantly. Meanwhile, it also maintains the 475℃ brittleness,high thermal conductivity and superplasticity characteristic of Ferritic stainless steel. Compared with Austenitic stainless steel, it has high strength, and the intergranular corrosion resistance and chloride resistant stress corrosion are obviously improved. Duplex stainless steel has excellent corrosion resistance and it is also a kind of nickel - saving stainless steel.
