Stock of Nickel Alloy 825 fasteners in Types of Hex Bolt, Stud Bolt, Threaded Rod, Lock Nuts and Washers

We manufacture bolts, nuts, anti-theft bolts & nuts, studs, foundation bolts, U-bolts, plain and spring washers in Incoloy 825 material in India. Incoloy 825 Socket Head Cap Screws are most popular fastener & can come with large cylindrical heads that have recessed hex-shaped drives. Due to this quality these Incoloy 825 Screws are mainly in demand by the applications where clearance is limited, and sockets and wrenches can't be used. The size of a Incoloy 825 metric screws or bolt is specified as diameter, pitch and length, in millimeters (millimeters is abbreviated "mm"). The size of Incoloy 825 nuts, will appear as diameter and pitch.

 

Table of Content


Incoloy 825 Fasteners shows immense resistance to many different highly aggressive corrosion environments. It is a nickel iron chromium alloy and it has in it parts of titanium, copper and molybdenum. Incoloy 825 Threaded Rod has a stable austenite structure. The nickel content in Incoloy 825 Screw is high and as such, it is capable of resisting chloride ion stress corrosion cracking. Because of the amount of copper and molybdenum that are present in Incoloy 825, it is thus able to resist acids and reducing agents. Incoloy 825 is titanium stabilized and as such, after fabrication, it is able to resist intergranular attack and pitting.


Incoloy 825 Bolt is highly capable of resisting oxidising conditions of the likes of oxidising salts, nitrates and nitric acid solution. Incoloy 825 Hex Bolt  is used in many applications such as nuclear fuel reprocessing, acid production, chemical processing, calorifiers, handling of radioactive wastes, expansion bellows, oil and gas recovery, pollution control, sulphuric acid piping and vessels, pickling operations and hot vessels for seawater, water and food. The Chemical Composition of Incoloy 825 is Nickel 38.0-46.0. Iron 22.0 min. Chromium 19.5-23.5. Molybdenum 2.5-3.5. Copper 1.5-3.0. Titanium 0.6-1.2. Carbon 0.05 max. Manganese 1.0 max. Sulfur 0.03 max. Silicon 0.5 max and Aluminum 0.2 max. Incoloy 825 Nut is one of the best cost effective options available today, in sulphuric acid service. Incoloy 825 shows very good resistance to corrosion by phosphoric acid and sulphuric acid. It is quite easy to machine Incoloy 825. ‘C’ alloy is how Incoloy 825 has been Classed as.
