Super Duplex Fasteners
Super Duplex 2507 Fasteners belong to the super duplex grade of steels. They have the qualities of ferritic and austenitic steel grades. There are three different types of duplex steels as standard duplex, super duplex and lean duplex. As a leading Super Duplex Fasteners manufacturer we produce the fasteners in all types and dimensions available. The super duplex is used most next to the standard duplex. The Super Duplex 2507 Bolts are costlier than the standard duplex and other grades of steel types because of their composition.
The material has 25% chromium, 4% molybdenum and 7% nickel in the content. The Super Duplex Stainless Steel Bolts and Nuts have very high corrosion resistance, especially the chloride ion corrosion cracking resistance. They are also resistant to pitting and crevice attack. Due to these qualities, the Super Duplex 2507 Hex Bolts are suitable for marine, sea water, brackish water applications such as water desalination plants. Other applications include flue gas scrubbing equipment, pulp and paper industrial applications, offshore oil drilling and production.
The Alloy 2507 Screws are used only with tools to drive them in and do not require nuts to hold them in place.

Alloy Steel Fasteners
The primary reason that has businesses choose using alloy steel over carbon steel grades is that their properties are noticeably higher. Unlike carbon steels, which provide the user with minimum to no corrosion resistance properties, Alloy Steel Fasteners Manufacturers In India recommend using steels belonging to this category, simply because their properties are better. Though in comparison the cost of using Alloy Steel Bolts for these applications makes the overall cost a little higher, the improvement of the properties makes it worth it.
Along with being tough, the Alloy Steel Stud Bolts generally display good behaviour when exposed to both low as well as high temperature settings. They have a higher tolerance to oxidation. Some grades of Alloy Steel Nuts, depending on their chemistry, have very high tensile strength, some of which are even better than conventional stainless steel grades. Not only is the Alloy Steel Washers hard, but they also have better durability and are able to take high pressure loads, without the fear of failure.
Unlike carbon steels that are hard and brittle, these fasteners have some form of ductility, which is important, especially if they are under duress. A small amount of ductility enables the Alloy Steel Screws to expand to such a degree that it is able to cater to the application, without breaking.

Carbon Steel Fasteners
Carbon Steel Anchor Fasteners are covered by ASTM A194 are designed to withstand being used in applications involving both high temperature and high pressure. Which is why per the specification the ASTM A194 Carbon Steel Hexagon Nuts are required to conform to the chemistry in addition to the test results.
The tests subjected to the Carbon Steel Industrial fasteners include hardness tests, cone proof load tests as well as proof of load tests. In order to improve the corrosion resistance properties of the Carbon steel Tooth Lock Washer, they are often galvanized. The thick coat of zinc applied on the carbon steel galvanised dash fastener improves their corrosion resistance properties in the presence of corrosive media, especially since carbon steels have poor resistance to corrosion.
Carbon Steel Fasteners Manufacturers recommend these fasteners to industries that prioritize the economics of the application rather than the longevity of the equipment used. However, this being said, one of the main advantages of using Carbon Steel Hex Domed Cap Nuts is their high toughness and hardness properties. These properties give the Carbon Steel Hex Head Screw an edge in sectors such as oil and gas as well as the petrochemical industry, where they are in high demand.

Aluminum Fasteners
Aluminum is known for its low density, making aluminum fasteners significantly lighter than steel or other metal counterparts. This characteristic is particularly advantageous in applications where weight is a concern, such as aerospace and automotive industries.
Aluminum naturally forms a protective oxide layer when exposed to oxygen, providing excellent corrosion resistance. However, aluminum fasteners may still corrode in certain environments, especially in the presence of saltwater or acidic conditions.
Aluminum is non-magnetic, which can be advantageous in applications where magnetic interference needs to be minimized, such as in electronic devices.

Titanium Fasteners
The mechanical properties of titanium will vary depending on the grade used. For instance, Titanium Bolts And Fasteners produced from alloys grade 1, grade 2, grade 3 and grade 4 are referred to as commercially pure titanium grades. Whereas the alloys after grade 5 Titanium 12 Point Bolts have different elements added in the alloy, thus improving some of its characteristics.

Copper Fasteners
Generally, the Copper Acorn and Coupling Nuts are used to fasten some areas of the boat or ship in order to improve its physical appearance. Aside from its physical appearance, the Copper Machine and Carriage Bolts exhibit good resistance to brine and saltwater, which indicates that they have a longer shelf life as they do not decay faster. Another reason why Copper Fasteners Manufacturers recommend using these fasteners in electronics is that copper is a metal that exhibits good conductivity to both heat and electricity, thus proving to be a useful component.
Furthermore, 110 Copper Threaded Rod has good bacteriostatic properties. Hence, after stainless steel grade 316, Copper Hex Bolts and Nuts are considered to be hygienic and therefore could be used in not only pharma industries, but also for the processing of food and beverage. Commercially pure Copper Bolts Nuts Washers are not only ductile and malleable, but they are also recyclable. Thus even defected fasteners such as the Copper Bolts And Nuts could be remelted and reused.
