Duplex Steel S32205 is an enhanced version of S31803, containing chromium, nickel, molybdenum, and nitrogen with a balanced austenitic-ferritic structure. The addition of nitrogen improves strength, toughness, and corrosion resistance. This alloy offers high tensile and yield strength, excellent resistance to stress corrosion cracking, and superior protection against pitting and crevice corrosion. S32205 tubing maintains mechanical stability, good fatigue strength, and impact resistance under high pressure and fluctuating temperature conditions.
