DESCRIPTION
Avesta Sheffield 2205 is a ferritic-austenitic stainless steel which
combines many of the beneficial properties of both ferritic and austenitic
steels. As a result of high chromium and molybdenum contents, the steel
has very good pitting and uniform corrosion resistance to stress corrosion
cracking as well as high mechanical strength.
2205 has good weldability and can be welded using most of the welding
techniques for stainless steels. Due to the balanced composition, when
welded correctly, the heat affected zone contains sufficient austenite
to avoid the risk of localized corrosion. The chemical composition of
2205 is balanced to give a microstructure containing roughly equal amounts
of ferrite and austenite.
DESIGN
FEATURES
• High strength.
• Low thermal expansion and higher heat
conductivity than austenitic steels.
• High resistance to stress corrosion cracking,
corrosion fatigue and erosion.
• High uniform corrosion resistance.
• High pitting and crevice corrosion
resistance.
• Good sulfide stress corrosion cracking
resistance.
TYPICAL
APPLICATIONS
• Heat exchangers, tubes and pipe for production and handling of gas
and oil
• Heat exchangers and pipes in desalination plants
• Pressure vessels, pipes, tanks and heat exchangers for processing
and transport of various chemicals
• Pressure vessels, tanks and pipes in process industries handling chlorides
• Rotors, fans, shafts and press rolls where the high corrosion fatigue
strength can be utilized
• Cargo tanks, piping and welding consumables for chemical tankers
TENSILE
REQUIREMENTS
Tensile Strength (KSI) 65
Yield Strength (KSI) 90KSI can be converted to MPA (Megapascals) by
multiplying by 6.895.
