Similar to the Inconel grades, the Incoloy grade alloys have both nickel and chromium as their primary base elements. The only difference between both these alloy classes is their chemical composition. While Inconel contain almost more than 50% of nickel in their alloys, whereas Incoloy not only contains less than 50% of nickel, but also contains iron in their alloys.
Table of Content
Chemically, Incoloy Fasteners consist of nickel, iron & chromium as their primary alloying materials. Besides these elements, the B425 N08825 have trace amounts of molybdenum, copper and titanium added to their alloy.
The ASTM B425 N08825 alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. Therefore it is used in many applications where there is a high demand for corrosion resistant materials. These fasteners are used as components in Pickling equipment like heating coils, tanks, baskets and chains.While similar to alloy 800, the astm b425 gr 825 is known to offer improved resistance to aqueous corrosion.
Apart from general corrosion, the Inconel 825 Fasteners has excellent resistance to both reducing and oxidizing acids. These Incoloy 825 Fasteners are also known to resist stress related corrosion cracking, localized attack such as pitting and crevice corrosion. Incoloy 825 is especially resistant to acids like sulfuric and phosphoric acids. Some of the main applications of this nickel steel Incoloy 825 Bolts includes its use in chemical processing plants, pollution control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.
In these environments, these Incoloy Bolts tend to exhibit good mechanical properties at both room as well as elevated temperatures that go up to approximately 1000°F.Incoloy 825 has a high level of corrosion resistance to intergranular corrosion. Apart from its excellent corrosion resistance, the cost of Incoloy 825 Fasteners is relatively cheaper, which is why they are used in a many applications including in pressure vessels, where the temperature can rise to as high up to 800°F.
