Unifit Metalloys Inc. is one of the noticeable traders and suppliers of Incoloy Alloy 825 Stud Bolts, which offer higher creep, stress-to-rupture and tensile strength at elevated temperature. The austenitic structure of Nickel Alloy 825 Stud Bolts gives excellent toughness, even down to cryogenic temperatures. Typical uses of Inconel 825 Stud Bolts include exhaust manifolds, furnace parts, heat exchangers, jet engine parts, pharmaceutical and photographic equipment, valve and pump trim, chemical equipment, digesters, tanks, evaporators, pulp, paper and textile processing equipment, parts exposed to marine atmospheres and tubing.
Due to the Mo-content, Inconel Alloy 825 Stud Bolts offers good resistance against media containing chlorides and non-oxidizing acids, because the resistance to inter-granular corrosion is guaranteed for larger product thicknesses in the welded condition. Depending on the application and performance requirements we also provide Incoloy UNS N08825 Stud Bolts, as they are high-performing in terms of tensile strength, durability, and corrosion resistance. UNS N08825 Incoloy Stud Bolts prove superior is its increased corrosion resistance — particularly against chlorides and chlorinated solutions.
Incoloy WNR 2.4858 Stud Bolts, the low carbon version of steel, is immune to grain boundary carbide precipitation (sensitization). These DIN 2.4858 Stud Bolts are austenitic alloys, meaning that these stainless steel products gain corrosion resistance from use of a nonmagnetic solid solution of ferric carbide or carbon in iron in the manufacturing process. N08825 Inconel Stud Bolts are high temperature resistant grades, and offers improved resistance to pitting corrosion in chloride environments.
