Application of Duplex 2205 Elbow

Duplex 2205 elbow fittings are widely used in various industries due to their excellent combination of high strength and corrosion resistance, particularly in chloride-containing environments.

Oil and Gas Industry
Chemical and Petrochemical Processing
Marine and Shipbuilding
Water Treatment and Desalination
Heat Exchangers

Benefits of Duplex 2205 Elbow Fittings

High Corrosion Resistance: particularly against pitting and crevice corrosion in chloride-containing environments.
Superior Strength: Higher tensile and yield strength compared to austenitic stainless steels like 304 and 316, allowing for thinner walls and lighter fittings.
Cost Efficiency: Due to their strength and durability, Duplex 2205 elbow fittings offer long-term cost savings in maintenance and replacements.
Good Weldability and Formability: Suitable for fabrication into complex piping systems without compromising material integrity.

Duplex 2205 elbow fittings are ideal for industries requiring high performance in harsh and corrosive environments while offering structural integrity and long service life.

2205 Stainless Steel vs 316

Duplex 2205 is ideal for high-strength and corrosive environments, especially in chloride-rich conditions where resistance to stress corrosion cracking and pitting is critical.

316 stainless steel is well-suited for less demanding applications where corrosion resistance in marine and chemical environments is important, but the strength requirements are lower.

Both alloys are highly valued in industries where corrosion resistance is crucial, but Duplex 2205 offers enhanced performance in more extreme conditions.

Is 2205 Stainless Steel Magnetic ?

Duplex 2205 stainless steel is slightly magnetic, but not as magnetic as ferritic or martensitic stainless steels.
