Nickel Alloy 825 Flat Washer Specification
- ASTM B425
- ASME SB 425
Incoloy is an alloy chemically composed of Nickel, chromium, and molybdenum. It is highly resistant to corrosion. Incoloy 825 has a high nickel content to resist chloride ion stress corrosion cracking and a stable austenite structure. The levels of molybdenum and copper enable them to resist reducing agents and acids. Chromium offers resistance to oxidizing conditions, such as nitric acid solutions, nitrates, and oxidizing salts. The Incoloy is titanium stabilized to resist pitting and intergranular attack after fabrication, particularly welding, which includes heating in the critical temperature range. Incoloy 825 Washers has outstanding features such as good machinability, tensile strength, excellent durability, and fabricability. These washers find their applications in Power Generation, construction, Paper & Pulp, marine, chemicals, and pharmaceutical industries. These washers are easily wieldable and come with a super finish. They are offered in various dimensions, shapes, sizes, and specifications and are also available in standard and nonstandard sizes.
