Super Duplex Steel 2507 Washer About

Super Duplex Steel 2507 washer is a high tensile and corrosion-resistant fastener part made from Super Duplex Stainless Steel 2507. It provides the endurance and dependability in severe climates.

Maximum Strength and Corrosion Resistance

Super Duplex Steel 2507 Washers are designed for operations demanding robust mechanical performance and corrosion resistance. The unique alloy composition (24-26% Cr, 6-8% Ni, 3-5% Mo, 0.24-0.32% N, Fe balance) imparts superior durability and resistance to pitting, particularly in chloride-rich environments. With a minimum yield strength of 550 MPa and minimum elongation of 15%, these washers maintain structural integrity under extreme conditions.

Versatile Applications Across Industries

Trusted worldwide, Super Duplex Steel 2507 Washers serve critical roles in petrochemical, oil & gas, marine, and chemical processing sectors. Their high impact resilience and operability between -50C to +300C make them ideal for load distribution, vibration reduction, and spacing in equipment assemblies. Each washer is produced to standard or custom sizes, ensuring a perfect fit for both specialized and general engineering needs.

Custom Manufacturing and Quality Assurance

Every Super Duplex 2507 Washer is manufactured as per ASTM A240/ASME SA240 standards, with dimensional accuracy to client drawings or established specifications. The washers feature burr-free, smooth edges, annealed temper, and a polished or clean pickled finish. Packaging options include corrugated boxes and plastic packets, ensuring safe transit and product integrity. With self-finished surfaces, no extra coating is required, providing cost-effective, reliable solutions.

FAQ's of Super Duplex Steel 2507 Washer:

Q: How is the Super Duplex Steel 2507 Washer manufactured to ensure high impact resistance?

A: The washer is annealed for enhanced ductility and then fabricated with burr-free, smooth edges. Its high impact resistance results from the dual-phase microstructure of super duplex steel and strict adherence to ASTM A240/ASME SA240 manufacturing standards.

Q: What packaging options are provided for Super Duplex Steel 2507 Washers?

A: Packaging includes durable corrugated boxes, gunny bags, or plastic packets. The final choice depends on the quantity ordered and specific customer requirements, ensuring product safety during transit and storage.

Q: Where can Super Duplex Steel 2507 Washers be effectively used?

A: These washers are ideal for petrochemical plants, oil & gas refineries, marine environments, chemical processing units, power stations, and general industrial equipment assemblies, especially where resistance to chlorides and harsh environments is crucial.

Q: What is the benefit of low magnetic permeability in Super Duplex Steel 2507 Washers?

A: Due to its duplex structure, the steel demonstrates only slight magnetism. This is advantageous in applications where minimal magnetic interference is necessary, such as sensitive measuring or control devices.

Q: When is it recommended to use a Super Duplex Steel 2507 Washer over standard stainless steel washers?

A: It is advisable to use Super Duplex Steel 2507 Washers when exceptional corrosion resistance, especially to chlorides, and high mechanical strength are required, including applications with exposure to aggressive environments or elevated stresses.

Q: How do customers specify custom dimensions, thickness, or diameter for these washers?

A: Customers can provide detailed drawings or select from standard sizes (M5-M100, thickness 0.5-12 mm) when placing orders. The manufacturing process allows for tailored dimensions, ensuring precise compatibility with client applications.

Q: What are the primary uses and benefits of Super Duplex Steel 2507 Washers in assemblies?

A: These washers provide optimal load distribution, decrease vibrations, and prevent direct surface contact in assembled equipment. Their durability and corrosion resistance lead to longer service life and reduced maintenance in demanding environments.
