Product Description

S31803/2205 1/4 Inch Duplex Stainless Steel Seamless Tube

 

Stainless Steel Seamless Tube:

 

Duplex S31803/2205 is a nitrogen enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels. 

 

The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance).
