Duplex 31803 Flat Washers and Spring Washers are fasteners made from Duplex 31803 stainless steel, which is a type of duplex stainless steel known for its excellent corrosion resistance and mechanical properties. These washers serve specific purposes in various applications, just like any other type of washer. Here's a brief overview of Duplex 31803 flat washers and spring washers:
Duplex 31803 Flat Washer:
Purpose: Flat washers, also known as plain washers, are used to distribute the load of a threaded fastener (such as a bolt or screw) over a larger surface area. They help prevent damage to the material being fastened and can provide stability and support.
Features: Duplex 31803 flat washers inherit the corrosion resistance and strength properties of the material. They are resistant to corrosion in harsh environments, making them suitable for outdoor, marine, and chemical processing applications.
Applications: Duplex 31803 flat washers can be found in various industries, including the oil and gas sector, chemical processing, marine engineering, and construction. They are used wherever the benefits of Duplex 31803 stainless steel are required to provide corrosion resistance and load distribution.

Duplex 31803 Spring Washer:
Purpose: Spring washers, also known as Belleville washers, are designed to provide a spring-like action when compressed. They are used to maintain tension in a fastener assembly, prevent loosening due to vibrations, and compensate for thermal expansion and contraction.
Features: Duplex 31803 spring washers offer the same corrosion-resistant properties as flat washers and are suitable for applications where vibration resistance and load retention are critical.
Applications: You can find Duplex 31803 spring washers in applications where maintaining tension in fastener assemblies is essential. Industries such as the automotive, aerospace, and machinery sectors often use spring washers to prevent fastener loosening in high-stress and high-vibration environments.
When selecting washers for a specific application, it's crucial to consider factors such as the type of load, environment, and the specific requirements of the fastener assembly. Duplex 31803 stainless steel washers can be an excellent choice in applications where corrosion resistance, strength, and durability are necessary.
