duplex 2205 round bar description

2205 duplex stainless steel round bar provides pitting and crevice corrosion resistance which in almost all corrosive media it is superior to austenitic stainless steels 316L and 317L.duplex 1.4462 roundbar also has low thermal expansion and high thermal conductivity as well as high corrosion and erosion fatigue properties than austenitic.

Duplex 2205 round bar advantage

Duplex 2205 round bar contain chromium of 22%, molybdenum of 3%, nickel of 5-6%, with high general, localized, and stress corrosion resistance properties in addition to excellent impact toughness and high strength.duplex hex bar should be annealed at 1900°F minimum, followed by rapid cooling, ideally by water quenching. And this treatment is valid for both solution annealing and stress relieving. Stress relief treatments at any lower temperature take the risk of detrimental intermetallic or precipitation of nonmetallic phases.
2205 duplex flat bar yield strength is about twice that of austenitic stainless steels and it allows a fabricator to save weight and makes it more cost competitive as compared to stainless steel 316L or
duplex square bar can be machined with high-speed steel tooling at the same feeds and speeds as stainless steel 316L. It possesses good weldability. The motive of welding duplex steel is that the weld metal and heat-affected zone retains the corrosion resistance, toughness and strength of the base metal. It is not difficult to weld it, but it is necessary to design welding procedures sot that it lead to a favorable phase balance after welding and will avoid precipitation of detrimental intermetallic or nonmetallic phases.
