Incoloy 800, 800H, 800HT Flat & Spring Washer, also known as UNS N08800, is a high-strength, corrosion-resistant nickel-iron-chromium alloy. This material is prized for its exceptional properties, making it a popular choice for a wide range of applications, including in the manufacturing of flat washers and spring washers.
Flat washers and spring washers are essential components in various mechanical and industrial systems. They serve different purposes and are designed to meet specific requirements. Incoloy 800 is an ideal material for these applications due to its unique combination of attributes.
Flat Washers (UNS N08800): Flat washers are used to distribute the load of a fastener, such as a bolt or nut, over a larger area. They help prevent surface damage and ensure a secure connection. Incoloy 800 flat washers offer several advantages:
Corrosion Resistance: Incoloy 800 is highly resistant to corrosion and oxidation, making it suitable for use in environments where exposure to high temperatures and aggressive chemicals is a concern.
High Temperature Strength: These washers maintain their structural integrity even at elevated temperatures, which is vital in applications involving heat or thermal cycling.
Excellent Mechanical Properties: Incoloy 800 flat washers exhibit good strength and ductility, ensuring they can withstand substantial loads without deformation.
Dimensional Stability: They maintain their shape and dimensions, even when exposed to extreme conditions, ensuring consistent performance.
