Incoloy 825 Flat & Spring Washer, also known as UNS N08825, is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. It is part of the Incoloy family of alloys and is known for its excellent corrosion resistance in a variety of environments, particularly in aggressive, high-temperature, and corrosive conditions. Incoloy 825 is often used in applications where resistance to sulfuric acid, phosphoric acid, and other harsh chemicals is required.
Flat Washer and Spring Washer are types of washers used in various mechanical and construction applications. Here's a brief explanation of both types of washers and how they can be made from Incoloy 825:
Incoloy 825 Flat Washer (UNS N08825):
A flat washer is a thin, flat, and circular metal disc with a hole in the center.
Incoloy 825 flat washers are typically used to distribute the load of a threaded fastener (such as a bolt or screw) over a larger surface area.
These washers can provide protection to the material being fastened and reduce the risk of surface damage due to pressure and friction.
Incoloy 825 is suitable for flat washers because of its excellent corrosion resistance properties. It can be used in applications where exposure to corrosive environments is a concern.

Incoloy 825 Spring Washer (UNS N08825):
A spring washer, also known as a lock washer, is a type of washer with a slightly conical shape. This shape allows it to exert a spring-like force when compressed.
Spring washers are often used to prevent fasteners from loosening due to vibration or thermal expansion/contraction. They create tension and provide a secure connection.
Incoloy 825 spring washers are ideal for applications where high-temperature and corrosive conditions may cause traditional materials to deteriorate. Incoloy 825's resistance to corrosion and high-temperature strength make it suitable for these washers.
Incoloy 825 is a suitable material for both flat washers and spring washers in environments where corrosion resistance and temperature resistance are important factors. These washers would be used in a variety of industrial applications, including chemical processing, petrochemical, and marine applications, where exposure to corrosive substances is a concern. The choice of washer type (flat or spring) and size would depend on the specific requirements of the application.
