Duplex Steel 2205 earns its strength from a thoughtful balance of chromium, nickel, molybdenum, and nitrogen. This unique composition gives it a mixed microstructure, combining the best qualities of both austenitic and ferritic steels. The result is a material with impressive yield strength and excellent toughness, all while maintaining strong resistance to stress corrosion cracking. It effectively bridges the gap between standard stainless steels and the more expensive super duplex grades.
