DESCRIPTION:
Alloy 2205 is a 22% Chromium, 3% Molybdenum, 5-6% Nickel, nitrogen alloyed duplex stainless steel with high general, localized and stress corrosion resistance proper-ties in addition to high strength and excellent impact toughness.
Alloy 2205 is a 22% Chromium, 3% Molybdenum, 5-6% Nickel, nitrogen alloyed duplex stainless steel with high general, localized and stress corrosion resistance proper-ties in addition to high strength and excellent impact toughness.
Alloy 2205 provides pitting and crevice corrosion resistance superior to 316L or 317L austenitic stainless steels in almost all corrosive media. It also has high corrosion and ero-sion fatigue properties as well as lower thermal expansion and higher thermal conductivity than austenitic.
The yield strength is about twice that of austenitic stainless steels. This allows a designer to save weight and makes the alloy more cost competi-tive when compared to 316L or 317L. Alloy 2205 is particularly suitable for applications covering the -50ºF/+600ºF temperature range. Temperatures out-side this range may be considered but need some restrictions, particularly for
welded structures.
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.
• 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.
