Introduction:
Duplex 2205 is two-phase,ferritic,austenitic 22% chromium,3% molybdenum,5 to 6% nickel alloyed stainless steel.It is the most widely used duplex stainless steel grade and is characterized by high yield strength,double that of the standard austenitic stainless steel grades.It also demonstrates good fatigue strength,as well as outstanding resistance to stress corrosion cracking,crevice,pitting,erosion,and general corrosion in severe environments.
SS2205 is a duplex stainless steel with a microstructure, when heat treated properly, of nearly equal proportions of austenite and ferrite. This microstructure ensures that SS2205 is much more resistant to stress corrosion cracking than SS304 or SS316L. The higher chromium, molybdenum and nitrogen contents give SS2205 significantly improved pitting and crevice-corrosion resistance in the presence of chlorides. SS2205 also has better general corrosion resistance than SS316L in most environments. In addition, SS2205 has a 0.2% Proof Stress of about double that of conventional austenitic stainless steels.
SS2205 has a ductile-to-brittle transition temperature of about –50°C. The stainless steel grade can also become embrittled when exposed to temperatures between 300°C and 550°C (475°C embrittlement) and 550°C to 1000°C (sigma [s] and chi [c] phase formation). Thus, application temperatures are generally limited from –50°C to 300°C.
SS2205 is a highly suitable material for service in environments containing chlorides and hydrogen sulfide, such as marine environments and the oil and gas extraction and processing industries. Typical applications also include the chemical industry (processing, transport and storage, e.g., pressure vessels, tanks and piping), the pulp and paper industry (digesters and liquor tanks) and the mining industry. SS2205 has thus found widespread use in production tubing and flow lines for the extraction of oil and gas from sour wells, in refineries and in process solutions contaminated with chlorides. SS2205 is also particularly suitable for heat exchangers where chloride-bearing water or brackish water is used as the cooling medium.
