About Duplex Steel UNS S31803 Washer

Duplex Steel UNS S31803 washers are manufactured from a high strength corrosion resistant austenitic-ferritic stainless steel alloy. This material is made of 50% austenite and 50% ferrite, which is strong and tough. These washers are widely used in many industries because of the product's versatility in various abrasive environments.

Superior Durability and Corrosion Resistance

Manufactured from UNS S31803 duplex stainless steel, these washers offer remarkable resistance to rust and corrosion, even in aggressive environments. The composition of chromium, nickel, and molybdenum provides resilience against pitting and crevice corrosion, making them a dependable choice for marine, chemical, and oil & gas sectors.

Adaptability and Customization

Whether you require standard or bespoke dimensions, these washers can be tailored to fit precise project specifications. Options for edge type, diameter (from 3 mm to 100 mm), thickness (0.5 mm to 10 mm), and finish make them suitable for a wide spectrum of engineering applications. Custom packing ensures safe and efficient delivery.

FAQ's of Duplex Steel UNS S31803 Washer:

Q: What is the magnetic property of Duplex Steel UNS S31803 washers?

A: Duplex Steel UNS S31803 washers show slight magnetic behavior due to the ferrite phase in their microstructure, which is inherent in duplex stainless steels.

Q: How are these washers protected against rust and corrosion?

A: They are made from a duplex stainless steel alloy with high chromium, nickel, and molybdenum content, offering excellent rust and corrosion resistance, especially in harsh industrial and marine environments.

Q: When should I specify customized dimensions or finishes?

A: Customization is recommended when you have unique size, width, thickness, or finish requirements not covered by standard offerings. We can manufacture washers as per your drawings or samples, ensuring they meet your exact specifications.

Q: Where can these washers be applied effectively?

A: These washers are extensively used in petrochemical plants, chemical industries, oil & gas facilities, marine engineering, power generation units, and various general engineering fields requiring robust load distribution and corrosion resistance.

Q: What is the manufacturing process for these washers?

A: They are produced following strict standards such as ASTM, DIN, JIS, and EN through processes involving annealing, deburring, precise cutting, and optional surface finishing like passivation, ensuring high-strength and quality testing at every stage.

Q: What benefits do deburred-edge washers provide during installation?

A: Deburred edges help prevent sharpness that could cause injury or equipment damage, ensuring safe handling, easier installation, and better performance under load and vibration.
