What is Stainless Steel Duplex 2205 Washer?

Stainless Steel Duplex 2205 Washers are engineered from a dual-phase microstructure consisting of both austenite and ferrite, providing superior strength, stress corrosion cracking resistance, and excellent durability. Duplex 2205 offers nearly twice the strength of standard austenitic stainless steels like 304 and 316, making these washers ideal for harsh environments, high-pressure systems, and chloride-rich applications.

Applications of Stainless Steel Duplex 2205 Washer

• Marine & Offshore Structures – Excellent resistance against seawater and chloride-induced corrosion.
• Chemical Processing Plants – Handles acids, solvents, and corrosive chemicals.
• Oil & Gas Equipment – Suitable for pipelines, rigs, pressure vessels, and subsea assemblies.
• Pulp & Paper Industry – Withstands corrosive bleaching chemicals and process fluids.
• High-Pressure Systems – Ideal for heat exchangers, reactors, and pressurized fittings.
• Structural Components – Used in load-bearing applications requiring high strength.

Common Uses of Stainless Steel Duplex 2205 Washer

• Used in bolted joints to ensure stability in corrosive and high-pressure environments.
• Ideal for marine fastener assemblies and underwater construction.
• Ensures secure fastening in pumps, valves, and industrial machinery.
• Performs reliably in environments involving temperature variation.
• Maintains strength and integrity under cyclic loads and vibration.
• Regularly used in desalination plants, heat exchangers, and refinery components.
