About Duplex Steel 2205 Washer

Duplex Steel 2205 washers are made from ferritic-austenitic stainless steel with high tensile strength and corrosion resistance. This material has the characteristics of both the ferritic and austenitic steels and is superior to the two in several adverse conditions.

Superior Mechanical Performance

Duplex Steel 2205 Washers deliver high tensile strength (minimum 620 MPa) and yield strength (minimum 450 MPa), along with reliable elongation properties. The dual-phase microstructure ensures enhanced durability and resistance to deformation, making them suitable for high-load and vibration-intensive assemblies.

Outstanding Corrosion Resistance

Specifically composed of 22% chromium, 5-6% nickel, and 3% molybdenum, these washers excel in resisting chloride pitting and crevice corrosion. This makes them ideal for marine, chemical processing, and other corrosive environments where protection and longevity are critical.

Customization and Flexible Sizing

Available from M5 to M100 and with thickness as specified, Duplex Steel 2205 Washers can be tailored to meet specific project requirements. Custom dimensions and finishes are offered to match technical needs, ensuring a perfect fit for each application.

FAQ's of Duplex Steel 2205 Washer:

Q: How does the duplex microstructure affect the magnetic properties of Duplex Steel 2205 Washers?

A: The duplex (austenite-ferrite) microstructure of Duplex Steel 2205 Washers results in them being slightly magnetic. This characteristic comes from the presence of ferrite, which imparts mild magnetism-unlike fully non-magnetic austenitic grades.

Q: What are the key benefits of using Duplex Steel 2205 Washers in corrosive environments?

A: These washers exhibit excellent resistance to pitting and crevice corrosion due to their high chromium and molybdenum content. This makes them highly effective for use in chemical plants, offshore structures, and other corrosive or chloride-rich settings.

Q: When should I choose a Duplex Steel 2205 Washer over standard stainless steel options?

A: Duplex Steel 2205 Washers are recommended when higher mechanical strength, better corrosion resistance, and durability are required than standard austenitic stainless steels like 304 or 316-particularly in demanding industrial or marine environments.

Q: Where are Duplex Steel 2205 Washers most commonly used?

A: These washers are typically employed in industrial assemblies, construction, piping systems, equipment mounting, and fasteners, especially where both mechanical strength and corrosion resistance are critical.

Q: What is the typical manufacturing process for Duplex Steel 2205 Washers?

A: The washers are manufactured through precision stamping, cutting, and machining processes, followed by finishing treatments such as polishing or passivation to ensure smooth surfaces and enhanced corrosion resistance.

Q: How does the machinability of Duplex Steel 2205 Washers compare to other stainless steels?

A: Duplex Steel 2205 has fair machinability. It requires appropriate tooling and reduced cutting speeds to handle its high strength and work-hardening rate effectively, compared to softer stainless steel grades.

Q: What are the available packaging and lead time options for Duplex Steel 2205 Washers?

A: Depending on order size and requirements, washers can be supplied in cartons, boxes, or pallets. Lead times are typically short for ready stock or can be arranged as per the specifics of your order.
