A Fastener is a device that mechanically joins two or more components together. Hastelloy Fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. We are a well known supplier of Hastelloy bolts, Hastelloy nuts, Hastelloy screws, Hastelloy studs and Hastelloy washers. Hastelloy C276 Fasteners are widely used in almost all types of industries. These Hastelloy C276 Fasteners are available in various shapes, sizes and designs. Fasteners manufactured by Siddhagiri Metals and Tubes conform to dimension standards like DIN 933, ISO 4017, DIN 931, ISO 4014, DIN 982, DIN 985, DIN 912, ISO 7380, DIN 7991, DIN 125, ISO 7379, DIN 127, DIN 1481, DIN 975, DIN 6923, DIN 934, DIN 7984. Our stock of fasteners range includes sizes 1/4" NB to 4" NB in Class 2000, 3000, 6000 and 9000. There are a variety of applications of fasteners in various industries such as automobiles, aircraft, appliances, agricultural machinery, commercial construction, and infrastructure. Fasteners can be divided into two main categories - non-permanent fasteners and permanent fasteners. Non-permanent fasteners (they enable parts to be assembled and disassembled repeatedly) can further be divided into two groups: General fasteners and Threaded fasteners. They are the most widely used type of non-permanent fasteners since they can easily be removed then reused.

Threaded fasteners are the principal devices used for assembling components and they are usually grouped into three main categories: Threads can be either external or internal:
External Thread: External threads are on the outside of a member (such as the threads of bolts and screws). A chamfer on the end of the screw thread makes it easier to engage it into a hole or a nut. An external thread is usually cut using a die or a lathe.
Internal Thread: Internal threads are on the inside of a member (such as the threads of nuts and holes). Usually, threaded holes have a chamfer on the side from which the screw will enter to make its engagement easier. An internal thread is usually cut using a tap.

Hastelloy Bolts: A bolt has a head on one end and threads on the other end and it is paired with a nut. Machine Bolt, Stove Bolt, J-Bolt, Hanger Bolt, U Bolt, Shoulder Bolt, Elevator Bolt, Hex Head Bolt, Carriage Bolt, Anchor Bolt, Eye Bolt are some of the types of bolts fasteners.

Hastelloy Screws: Screws are used to join two mating parts together and similar to bolts, they have the head on one end and threads on the other end. However, screws usually have longer threads than bolts, also they can be made with slotted heads. Screws are further divided into two sub-categories; Cap Screws and Machine Screws. Machine screws are generally smaller in size than cap screws and they are used for screwing into thin materials.

Hastelloy Setscrews: Setscrews are a special type of screws that usually does not have a head and they are used to prevent rotation or movement between parts (such as a shaft and a collar). A Setscrew is driven through one member such that it will apply a compressive force on the other member while a screw or a bolt clamps the two members together.

Hastelloy Studs: A Stud is a rod that is threaded on both ends and joins two mating parts. A nut may be used on one end.

Hastelloy Nuts: A Nut is the counterpart of a bolt. Bolts and nuts are used together to clamp two or more parts having unthreaded holes together. Our supply of Hastelloy Nuts are Hex Nuts, Wing Nut, Castle Nut, Flex Lock Nut, High Nut, Coupling Nut, Cap Nut, Acorn Nut, Flange Lock Nut, Jam Nut, Flange Nut, Square Nut, Nylon Lock Nut, Slotted Nut, T-Nuts, Heavy Hex Nut.

Washers: Washers are commonly used under the heads of bolts and screws and they are used under nuts as well. The most common type of washers is the Flat Washer, where it is used to increase the bearing areas of the head, and protect the material finish during assembly. The use of washers also prevents the sharp corner of the hole into which the bolt or screw is being inserted from biting into bolt head fillet where that can cause the failure of the bolts during service. Our stock range of Hastelloy washers are Lock Washer, Spring Washers, Dome Washer, Fender Washer, Tab Washers, Plain Washer, Flat Washer, Hexagonal Washer, Square Washer, Dome Tooth Washer, Split Washer, Countersunk Washer, Tooth Lock Washer, Dock Washer, Ogee Washer, Hex Washer.

Properties of Hastelloy C276 alloy

Hastelloy C276 Cold Forming

Annealed treatment is followed for every forming operations. For cold deformation at high-level, cold forming is done for the deformation process where cracking is a possibility because of mild forming. The cold forming process is used to restore the resistance to stress corrosion cracking. For most of the time, a solution anneal is recommended after the complete formed or annealed operation which helps to restore the material to its optimum condition and properties.

Hastelloy C276 Hot Forming

Hastelloy C276 can be hot-worked into various forms but they are more sensitive to the amounts and rates of hot-reduction with the austenitic stainless steels. During Hot working, all parameters should be taken into account. Special attention should be given to the temperature at which the alloy begins to melt. The high strengths of the Hastelloys at elevated temperature, their low thermal conductivity, and their hardening rate. Moreover, when the temperature is low in the hot working range of the metal, they are resistance to deformation is increased rapidly. So, while hot working practices that give heavy initial reduction followed by moderate final reductions, also with frequent re-heating gives the good result.

Hastelloy C276 Machining

Hastelloy C276 can be machined using conventional production methods at satisfactory rates. During the machining processes these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. Following are key points that should be considered during machining operations: Capacity, Tooling, Lubrication/Coolants, Drilling. The actual operating parameters are to serve only as a guide and are not to be taken as absolute values.

Hastelloy C276 Welding

Gas tungsten-arc welding, gas metal-arc welding, shielded metal-arc (coated electrode) welding, or resistance welding may be used. Minimum heat input consistent with adequate penetration reduces the chance of hot-cracking. Oxyacetylene welding should be avoided due to possibility of carburization. Hastelloy C-276 can be used in the as-welded condition in most chemical and petrochemical process equipment

Hastelloy C276 Heat Treatment

Wrought forms of Hastelloy C-276 are furnished in the solution heat-treated condition unless otherwise specified. Alloy C-276 is normally solution heat-treated at 2050 °F and rapid quenched. Parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation, if possible
