Fasteners of Diverse Materials

Duplex and Super Duplex Fasteners

Super Duplex Nuts And Bolts Manufacturer In All Shapes, Sizes, And Standard, Maintain Stock Of Super Duplex 2507 Hex Bolts In India.

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.

Inconel Fasteners

Inconel is a family superalloys whose basic chemical composition consists of nickel and chromium. Inconel grade alloys have an austenite microstructure. One of the best features of the Inconel Socket Head Cap Screws are its superior resistance to oxidation corrosion. On account of a high content of chromium in the Inconel alloy, there is a passivate oxide layer formed on the surface of these fittings.

This passivate oxide layer protects the Inconel Nuts And Bolts from oxidative corrosion, otherwise known as rusting. Since Inconel alloy has good resistance to oxidation corrosion, the fasteners manufactured from this alloy are well suited for applications where the equipment’s are subjected to extreme heat and pressure environments.

At elevated temperatures, Inconel maintains its high tensile strength, thereby proving to be attractive for applications at elevated temperatures where metals like steel and aluminium would succumb to creep. The high tensile strength of the Inconel Nuts And Bolts is attributed to precipitation hardening or solid solution strengthening processes. When trace amounts of niobium is added to in combination with nickel to the Inconel Exhaust Bolts, there is a formation of an intermetallic compound known as gamma double prime.

Hastelloy Fasteners

Hastelloy is group of nickel based super alloys. This grade of alloys is also known as high performance alloys by Hastelloy Bolts Supplier. Hastelloy Nuts and Bolts are known for their high resistance to corrosion. The corrosion resistant properties of the Hastelloy Washers are attributed to the high content of nickel present inthem.

Hastelloy Bolts is a nickel molybdenum chromium superalloy with additions of iron and tungsten with extreme resistance to corrosion at high temperatures. There are also many different grades of Hastelloy Fastener available. Most of these Hastelloy Screws were designed specifically for high temperature applications. Hastelloy Studs has outstanding resistance to highly oxidizing and reducing agents, making it a great choice for moderate to severe corrosive environments.

Titanium Fasteners

Some of the best features of Titanium Fasteners includes its Excellent strength to weight ratio & its inert behaviour to chlorine containing compounds and seawater.Similar to some grades of stainless steel that have a passivated oxide layer, Aerospace Titanium Fasteners too have the ability to regrow their protective passive layer rapidly in the presence of oxygen and a minimum of 50ppm of moisture.

This is the reason why Titanium Screws have an unrivalled resistance to saline environments. They are resistant to elevated temperatures and high velocity in both moving currents ad well as in stagnant water. Titanium Nuts are resistant to high velocity, rapidly moving currents as well as stagnant seawater, and they aren’t affected by the presence of sulphides in marine environments.

Although they have good resistance against chlorine, titanium isn’t resistant to reducing acids and media. The protective layer formed on titanium protects the fasteners from oxidation resistance. In Oxidizing environments, the absence of water can cause Titanium Bolts And Fasteners to rapidly corrode or even ignite.

Titanium Bolts And Fasteners are not only strong, but also lightweight. In terms of strength, is almost 4 times stronger in comparison to 316 grade stainless steel, which is two times heavier than the said metal. This property makes them ideal to be used as Titanium Aircraft Fasteners in the aircraft, sports and medical fields.

Besides these features, Titanium Threaded Rod is resistant to corrosion. Hence the Titanium Alloy Washers are an used in industries like marine, chlor- alkali, desalination, offshore, medical, pulp & paper as well as the oil and gas industries. These industries, not only demand a corrosion resistant alloy, but also a strong one. Therefore Titanium Alloy Washers are well suited to them.

Tantalum Fasteners

A shiny-grey metal having a density of 16.6 g/cc and melting point of 2996 degC. It is extremely corrosion resistant, soft and ductile which makes it useful for chemical processing plant, medical implants and as additions to super-alloys where enhanced elevated temperature strength is required.

Tantalum is one of the most inert metals known, it is resistant to most acids and corrosion and non toxic to the human body. Consequently it is used extensively in the chemical industry for processing equipment, and in the medical industry for joint replacements and medical implants. Almost every high quality electronic gadget or device you can think of will include a Tantalum Fasteners capacitor. Tantalum Bolts are highly heat and corrosion resistant, whilst retaining strength for high stress applications, making them ideal for use in industrial gas turbines, jet engines, ballistics and chemical processing. We stock most ANSI standard sizes and have a same day shipping policy. Please see below for tantalum refractory threaded rod sizes and standard lengths. We can also cut to specific lengths. Also in stock are compatible nuts and washers.

Plastic and Nylon Fasteners

Plastic Fasteners are considered a viable alternative to metal components due to their strong, lightweight and versatile characteristics. Nylon is cost-effective material that is rust-proof and non- conductive. It also provides good levels of chemical and corrosion resistance.

We supply a wide range of non-metallic fasteners, found across a variety of industries and applications. This includes threaded rods – primarily used to connect two materials together, as well as a selection of screws, nuts, washers and spacers. These fasteners are often supplied in a white (natural) colour as standard, but can be dyed in a huge range of colours to suit any application or assembly.

Standard sizes are available to order with short lead times, while non-standard sizes and materials are also available to order on request.
