Types of Fastener Materials

Fasteners are a prominent part of mechanical systems. They are essential for connecting multiple elements of the system. These accessories help connect almost all machinery and equipment. Fasteners are available in different types, like belt fasteners, bolts, nuts, washers, and screws. Each fastener has distinct characteristics depending on its applications. Selecting the right fastener type is crucial. One must consider the fastener materials and its grades. When one gets a clear idea of the fastener material and its grades, it is easy to understand the alloy mixture and hardening processes to select the right fastener for your application.

Why does fastener material matters?

A reputed stainless steel fastener supplier in India like Doshi Impex India features an extensive range of fasteners in different materials and plating. It also helps determine the fastener’s corrosion resistance and aesthetics. One can understand the following aspects of fasteners like brass screws, bolts, washer bolts, and more:

• Strength
• Corrosion resistance
• Brittleness
• Galvanic corrosion
• Price

Fastener material is crucial even when replacing the fastener. One must match the material of the fastener during its replacement as it will prevent the system from failing or damaging critical or expensive elements. Considering the project environment is also crucial when selecting fastener material. For instance, saltwater applications can cause galvanic corrosion meaning the fastener material must be highly corrosion-resistant.

Fastener materials

The following are the top fastener materials available at Doshi Impex India, the leading fastener manufacturer in India:

Stainless steel fasteners

Stainless steel is an alloy of chromium and low-carbon steel. The alloy has high corrosion resistance and an affordable price. The corrosion resistance properties of fastener material are crucial as it can lose its resistance. It is essential to note that is a common misunderstanding that stainless steel is not as strong as standard steel. The low carbon in stainless steel alloys does not get hard during heat treatment. Stainless steel alloys often find application for making bolts more than standard steel.

Steel fasteners

Steel is another widely used fastener material that has a plain surface and does not have surface treatments. They are also devoid of galvanization and zinc or chrome plating. Steel fasteners are available in different grades like- alloy steel and grade 2, 5, and 8.

Alloy steel fasteners

These fasteners use steel alloys of high strength. Steel bolts and other steel alloy fasteners often do not have the plating. It means they have a blackish appearance. These fasteners have high strength and are brittle.

Aluminum fasteners

Aluminum fasteners have high corrosion resistance, like stainless steel fasteners. The corrosion resistance of aluminum belt fasteners is not affected by scratches or nicks. Soft aluminum fasteners utilize an extensive range of alloys and consist of elements like copper, iron, manganese, zinc, copper, or silicon. The silicon content in these fasteners helps to elevate the strength and melting point of the fasteners.

Chrome plating fasteners

These fasteners have a shiny polished appearance due to chrome plating. It offers similar corrosion resistance to zinc plating on fasteners. These fasteners are however slightly expensive but have an extensive finish to the equipment.

Silicon bronze fasteners

It is another type of fastener material. Most times, bronze is considered similar to silicon. It is an alloy made of copper, tin, and minor silicon additions. These fasteners find applications in the marine industry and corrosive environments. These fasteners have high strength and exceptional corrosion resistance. These fasteners have a high cost however, these can be a perfect choice depending on the fasteners.

High Nickel Fasteners

High Nickel Fasteners are extensively used for leak proof repairing of piping or tubing systems, which is used for conveying various liquid. To ensure high standards of quality, the offered products are manufactured using latest technology and sophisticated machinery. Our High Nickel Alloy Fasteners are accessible to our valuable customers in different range of diameters, wall thicknesses and sizes at quite affordable rates. Meanwhile, these fasteners are available in different dimensions and material to ensure wider choice to our clients.

Titanium Fasteners

Titanium is a low density material, which means that it is ideally meant for applications that require lightweight components. Since the vehicle has to gain momentum at a rapid pace, using lighter weighing Aerospace Titanium Fasteners aids it to achieve that. The density of the material is lower than that of stainless steel alloys. Doshi Impex India is best manufacturers & suppliers of Titanium Alloy Fasteners, which has very good mechanical properties at both elevated and sub – zero temperatures. We also offer the same in different grades such as Titanium Grade 2 Fasteners, Titanium Grade 5 Fasteners, and so on.

How can you select the right fastener materials and material grade?

A reputed fastener and pipe fitting manufacturer in India offers quality markings on the fastener head. It indicates the fastener grade. One can determine the fastener grade from markings like six or three radial lines. If you are unsure of the fastener material selection, consult experts at the leading stainless steel fastener Supplier in Mumbai, like Doshi Impex India.
