What is 2205 Duplex Stainless Steel?
2205 Duplex Stainless Steel is a high-performance alloy that combines the mechanical properties of both austenitic and ferritic stainless steels. This unique best composition makes duplex 2205 more stronger and corrosion resistant to be used in high temperature applications. Duplex SS 2205 consists of 22% chromium, 3% molybdenum, and 5-6% nickel offers outstanding resistance to pitting and chloride stress corrosion cracking. Its high mechanical strength allows it to reduce material thickness, making it a cost-effective solution. Due to its exceptional weldability and durability, Duplex 2205 is widely used in heat exchangers, acid tanks, pipelines, and other applications rather than traditional stainless steel material.
