The Incoloy grade alloys, like the Inconel 800 Grades, have nickel and chromium as its main basis components. The chemical makeup of the two alloy types is the only distinction. While Incoloy not only has iron in its alloys but also less than 50% nickel, whereas Inconel's alloys almost contain more than 50% nickel.
Table of Content
Chemically, nickel, iron, and chromium make up the majority of the alloying components in incoloy fasteners. In addition to these, the alloy of the B425 N08825 also contains trace amounts of molybdenum, copper, and titanium.
The chemical makeup of the ASTM B425 N08825 alloy is created to offer high resistance to numerous corrosive conditions. Due to the high demand for corrosion resistant materials, it is utilised in numerous applications. These fasteners are used in the chains, tanks, baskets, and heating coils of pickling equipment. Even though it resembles alloy 800, astm b425 gr. 825 is known to provide better protection against aqueous corrosion.


The Inconel 925 Fasteners exhibit exceptional resistance to both reducing and oxidising acids in addition to normal corrosion. These Incoloy 825 fasteners are also noted for their ability to withstand localised attacks such pitting and crevice corrosion as well as stress-related corrosion cracking. Particularly resistant to acids like sulfuric and phosphoric acids is incoloy 825. Its use in chemical processing plants, pollution control machinery, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment are just a few of the main applications for these nickel steel Incoloy 825 Bolts.
These Incoloy Bolts typically have good mechanical characteristics in these conditions, both at ambient temperatures and at increased temperatures up to about 1000°F. Intergranular corrosion is highly resistant to Incoloy 825 corrosion. Incoloy 825 Fasteners are used in many applications, including pressure vessels where the temperature can rise to as high as 800°F, due to their excellent corrosion resistance and relatively low cost.
