2205 stainless steel tube is the most widely used duplex (ferritic/austenitic) stainless steel. Because of its high chromium, molybdenum and nitrogen contents, duplex 2205 offers excellent general corrosion resistance and localised corrosion including intergranular, pitting and crevice corrosion. The grade is also resistant to chloride stress corrosion cracking at temperatures of up to about 150°C.
