INCONEL 718/825 NUT:


DC is one of the leading entities that offer a wide range of Inconel 718/825 Nuts to different industries. The products that we feature have unique properties and qualities, which leads them worthy across the markets. Delivering products on time is our first preference. We provide it in the least or given time.

Inconel 718/825 Nuts have essential elements in the material composition, such as nickel and chromium as the primary composition. Apart from this, they also have chemicals like copper, molybdenum, and titanium-like elements. The common properties between both alloys are good corrosion resistance and resistance from general corrosion, including opposition from reducing acids and stress corrosion cracking, also resists localized acid attacks like sulphuric and phosphoric acids. Inconel 718/825 alloy is used across many high-treating environments where high corrosion resistance is required, such as heating coils, tanks, baskets, and chains. Inconel 825 alloy, also similar to Inconel 800 alloy in terms of improved resistance over aqueous corrosion. Inconel 718/825 fasteners, including nuts, have applications comprising pressure vessels, oil and gas piping, nuclear fuel reprocessing, acid production, etc. Inconel 718/825 nuts have good mechanical and physical properties at room temperature to the high-temperature atmosphere up to 1000 degrees F. Inconel 825 grade has better corrosion resistance and intergranular corrosion than some other grades.We offer a variety of shapes, sizes, and dimensions of nuts, even custom-made products for our esteemed clients worldwide.
