Incoloy 825 Fasteners: Bolts, Screws, Stud Bolts, Nuts, Washers

AISI 4130 Bolts

Incoloy 825 fasteners forms an integral part of our initial product line. BoltPort is an eminent manufacturer and supplier of Incoloy 825 fasteners such as stud bolts, hex bolts, heavy hex bolts coupled with hex and heavy hex nuts, plain washers, spring washers, etc. These alloy 825 fasteners are hot formed and stock in semi finished form at our facility. Upon order, these semi finished products are machined and delivered without much lead time. We have expertised in manufacturing alloy Incoloy 825 fasteners. Incoloy bolting components are available in metric and imperial (inch) sizes with ISO, Unified National UN, UNC, UNF, UNEF, BSW & BSF thread profiles. Incoloy 825 is quite commonly classified among Inconel alloys.

Common Incoloy 825 fastening products includes hex bolts, heavy hex bolts, stud bolts, full threaded studs, tap end stud bolts, set screws, hex nuts, heavy hex nuts, plain washers, etc. Alloy 825 fasteners are used for high temperature bolting applications in chemical and petrochemical processing, oil & gas refining, heat processing equipments, etc.

About Incoloy® 825

Incoloy 825 is a nickel-iron-chromium alloy with addition of molybdenum and copper elements. Alloy 825 is designed to exhibit exceptional resistance to many corrosive environments. Incoloy 825 is quite similar to Incoloy 800 but with improved resistance to aqueous corrosion. Alloy 825 has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Incoloy 825 is also resistant to sulfuric and phosphoric acids environment pavings its way into chemical process streams. Incoloy 825 is widely used for bolting application in oil & gas extraction, nuclear fuel processing, acid production and pickling equipment manufacturing.
