Different Applications Of Cold Rolled Steel

March 8, 2022

We have heard of steel being used in every process where durability and strength matters. We even know that steel cannot be used directly in the application and must be fabricated according to the needs. So, cold rolling is one such fabrication process to enhance the physical properties of the steel. In the cold rolling process, the steel dealers or manufacturers strengthen the steel by changing its shape without heat or pressure. The large steel coils are passed through the two parallel rollers keeping the temperature below the steel’s recrystallization temperature. Thus, the steel coils unwind, and each steel strip is squeezed and compressed. Hence, the resulting metal strips have increased hardness and yield strength. Therefore, one can say that cold rolling the metal strips is one of the significant functions in metalworking industries. Hence, in this post, let us see the different applications of cold-rolled steel in various industries.

Cold-rolled steel in construction:

The foremost application of cold-rolled steel is in the construction and development sector. We all know that steel is essential to make your building stand against the various climatic conditions. Similarly, cold-rolled steels are used significantly in the construction industry for framing purposes. The cold-rolled steels are light in weight and yet stronger than other metal framings. The cold-rolled framings are used in multi-storey building construction like hotels, dormitories, and related structures.The cold-rolled MS chequered plate are even used for the flooring purposes.

As mentioned earlier, cold-rolled steel is less in weight, and hence it can be shipped and assembled later. Similarly, the cold-rolled steel exhibits high tensile strength; it is sufficient to use fewer steel materials for structural support and reduces resource consumption. The cold-rolled steel is used in making bolts and screws for metal sheeting and sheeting rails.

Cold-rolled steel in home appliances:

Another application of cold-rolled steel is that they are used in home appliances extensively. It is hard to find even one home appliance without cold-rolled steel. The cold-rolled steel is used in washers, dryers, water heaters, computer hardware, refrigerators, and related household things. One can find numerous domestic appliances with cold-rolled steel because they have a higher tolerance than the other metals. Similarly, these steels have excellent tensile and yield strength, making them an ideal material for home appliances. Hence, cold-rolled steel is one such versatile material with an exceptional surface finish.

Cold-rolled steel in pressure vessels:

Pressure vessels are enclosed containers where the core of any material is placed under extreme pressure. These vessels play a vital role in the petrochemical and nuclear plants. The cold-rolled steel is used in the pressure vessels because of their elongation rate, toughness, embrittlement, and fatigue strength. Hence, because of their exceptional physical properties, cold-rolled steel is used in the pressure vessel to compress the overall pressure produced by the vessel. However, the size and pressure of the vessel differ from country to country, depending on the country’s formal code.

Hence, these are the different applications of cold-rolled steel in various sectors. Bharat Steel – the best JSW steel dealers in Chennai who offer quality steel products at good standards.

Differences Between Seamless And Welded Steel Pipes

February 26, 2022

The steel pipes play a vital role in transmitting oils, gases, and water in various industries. These are cylindrical tubes made from raw steel materials undergoing various transformation processes. Have you heard of seamless and welded pipes? Pipe welding or welded pipes is where the two pipes are joined by using the welding techniques. The seamless pipes are single hollow pipes in the middle and do not have visible welded marks or lines, unlike welded pipes. However, it becomes a debate while choosing the welded and seamless pipes. Many steel dealers in Chennai suggest selecting the pipes depending on the purpose and requirements of the project. The differences between seamless and welded steel pipes are based on production methods, cost, resistance, and related factors. Hence, in this post, let us briefly see different techniques that vary them.

Production method:

The foremost difference between the seamless and welded pipes is the production method. The seamless pipes get that smooth finish by undergoing an extrusion process. The raw casted steel billets are placed inside the heating chamber at a high temperature, offering a sufficiently strong force with the piercing machine to create a hollow. However, various casting methods are employed to produce seamline pipes with perfect smooth consistency outside.

In the welded pipes or Electronic Resistance Welding method (ERW), the steel sheets are rolled continuously till the cylindrical shape is achieved. However, an electric current is passed at the end of the pipes, which melts and combines them. The ERW method is used for welding MS chequered plate, sheets, and strips for commercial and industrial purposes.

Hardness:

Another significant difference between the seamless and welded pipes is the strength or hardness. Pipes are used majorly for transmitting fluids and gases. In the case of fluid transmission like water, the pipes should be able to handle the pressure of the water. If the tube is used for units like air conditioning, it should be prone to different temperatures.

The welded are less prone to varying temperature and high pressure. The welded lines on the pipes can detach the pipes from one another under varying environmental conditions. Due to the absence of welded seams in the seamless pipes, the pressure is evenly distributed even at different temperatures, making them ideal for transmission.

Rust-resistance:

Thirdly, manufacturers can provide rust or corrosion resistance to the metals through the galvanization process. The metal, for example, a SAIL TMT bar, must be hot-dipped in a bath filled with molten zinc. So, after removing them from the bath, the zinc reacts with the metal and forms a layer that is resistant to corrosion.

The galvanization for the welded pipes does not stay longer due to chemical and environmental factors. The welded joints react with the zinc and lead to deposits that can eventually lower the quality of the material. In the case of seamless pipes, the zinc coating adheres well with the surface of the metal due to the lack of welded joints and extrusion process.

Hence, these significant differences differentiate welded and seamless pipes. However, choosing the appropriate pipe depends entirely on the project’s purpose. Bharat steel is the best JSW steel dealers in Chennai and provides quality steel pipes used extensively for all transmission purposes.

Three Types Of Press Brakes In Steel Fabrication

February 22, 2022

People working in the steel manufacturing industries and factories know that fabricating steel is not an easy job. Steel fabrication involves cutting, punching, stamping, shearing, and welding to get the desired steel form. Thus, the steel dealers or the manufacturers use press brakes to fabricate. Press brakes are the pressing machine or device that bends the metal sheets and plates under high pressure and strength. The bends on the metal sheets are made by clamping the matching punch and dye. However, with the help of science and technology, the press brakes machines are further classified depending upon their process. So, those working in the metal industry will at least learn and work with any of these types. Hence, a better understanding of the three types of press brakes in steel fabrication will be an additional advantage in this field. Therefore, let us know more about each press brakes type and its uses for many steel suppliers in Chennai.

Manual Press Brake:

As the name suggests, the manual press brakes are operated manually and were popular 50 to 60 years ago. These machines are also called sheet metal brakes, and the machine operators should feed the data manually. Hence, the operator should know about the machine’s dynamics and mechanics to set the angles and dimensions of the steel manually. Thus, the operator should repeatedly change the machine’s settings for different materials that too manually, which can consume more time. Therefore, these machines are used only for mass production. However, this equipment does not cost much but is not suitable for this fast-growing world. The manual press brakes are inefficient if you fabricate MS chequered plate for flooring with different angles and dimensions.

Hydraulic Press Brake:

Another popular pressing machine that matches today’s dynamic environment is the hydraulic press brakes. The hydraulic press brakes include a hydraulic cylinder that moves the machine’s RAM for the process. The hydraulic machine can bend the steel sheets up to 8cm and provide pressure around 1,200 tons. Thus, the hydraulic brake pressing machine offers greater yields and better control to the operator. The only concern about this machine is that they work within their tonnage rating and consume more power even when idle. However, it is used widely from industrial applications to the rebars and SAIL TMT bar production line.

CNC Press Brakes:

Thirdly, CNC or Computer numerically controlled press brakes are computer-aided machines that have made the operators’ job easier. These machines work on the servo motors with accessible pressure control, making the cutting more precise and accurate. The CNC press brakes have more tonnage rating and only use electrical conduction while working. The operator has only set the dimensions and angles for fabricating using the setting provided and can be changed per requirements. It is worth investing in this equipment to yield better results with lower energy consumption.

These are the three mainly used metal pressing machines by leading steel manufacturers. Bharat Steel – the best MS steel suppliers in Chennai, offer quality metal sheets with precision and accuracy with the help of press brakes depending upon project or business.

Welding Tips To Fabricate Carbon Steel

February 12, 2022

Steel is one of the most versatile products as it can be fabricated into any shape. Do you know why the welding process is more prevalent in the steel industry? Welding is a process where you can fuse two or more steel products into a single product through pressure, heat, or both. Many steel dealers in Chennai find welding the prime solution for fabricating metals in pharmaceuticals, petrochemicals, food and beverage, and related industries. One of the significant concerns in carbon steel is they don’t distribute the heat evenly. Thus, it makes the carbon steel rust, embrittlement, and warping. Hence, in this post, let us see some welding tips to fabricate carbon steel for even heat distribution.

Right filler metal:

The foremost welding tip to fabricate carbon steel is to choose the suitable filler metal. The filler metal refers to the unalloyed or alloy metals that are heated, melted, liquified, and allowed to flow between the space of two joining metals. This filler metal gives the welded metals the required strength and corrosion resistance. So, the filler metal that you will use to weld the carbon steel can affect the output material’s quality and strength. Thus, to choose the suitable filler metal, first, consider the dimension of the metal that is going to be welded and the filler metal. The filler metal should be thinner or equal to the base metal; otherwise, the weld will be too weak.

Similarly, the base and filler metal should have the same chemical composition because different chemical properties can weaken the welding process. For example, if you are welding 316 austenitic stainless steel, the steel suppliers use 316L metal as a filler metal. The letter “L” refers to the low carbon content and trace level.

Preparations:

Another excellent tip to consider in fabricating carbon steel is proper welding preparation. We all know that carbon steel is one of the sensitive steel and gets contaminated by dirt and dust particles easily. So, while welding the carbon steel, make sure that your workstation and instruments are clean enough. If not proper preparation is done, it can consecutively reduce the corrosion resistance and strength of the metal. Similarly, use a brush dedicated only to clean the carbon steel. The JSW steel dealers in Chennai offer the best carbon steel for various industrial and commercial purposes.

Gas coverage:

Thirdly, give the welding the maximum gas coverage to reduce the oxidation level. While welding the metal, use enough shielding gas and a bigger face shield rather than increasing the gas input. Similarly, ensure that the input gas or shielding gas should be chosen wisely because it can affect the properties of the metals. The shielding gas combinations commonly used are argon and carbon dioxide, helium, argon, and carbon dioxide or argon and oxygen.

Hence, use these tips to fabricate your carbon steel effectively with proper heat distribution. Bharat Steel is the best steel dealer in the city, offering products like SAIL TMT bar, steel tubes, pipes, and many more with high quality and precision.

Various Applications Of Steel Tubes

January 17, 2022

Have you ever heard of steel tubes? Steel tubes are similar to columns that are cylindrical tubes that are used from industrial to structural uses. At the first glance, you may find that the steel tubes and steel pipes are similar.

However, they vary from each other in every aspect. Generally, steel pipes are used for the transmission of oil, water, and natural resources. But steel tubes are used as a part of the construction industry to support the structures. Hence, steel suppliers in Chennai provide steel tubes in different shapes like square, rectangle, or circular to meet the building requirements. The properties of the steel tubes are similar to the steel pipes, and many steel dealers use only high-grade steel for these tubes.

These steel tubes are durable, have high tensile strength, and are made into desired shapes for structural adjustments. Hence, in this post, let us know the various applications of steel tubes.

Columns:

The steel tubes are used in the construction industry as columns to support the structure. These longitudinal steel columns are used to bear the loadings of the buildings. Steel columns can be specially used for high-raised structures because they offer high stability and resistance to chemicals, abrasions, and fluids. So, building contractors use steel tubes in place of reinforced concrete. The prolonged exposure of concrete to moisture can make them weak and cause deformation. Thus, steel tubes are the best for the building columns because their hollow structure allows them to perform better. However, you might need additional fittings and structural arrangements to work efficiently with steel tubes but the extra arrangement does not cost much. Therefore, by using the steel tubes you can have an efficient building process.

Railings:

In some places, steel tubes are used in the railings, and you can find them in stairs, decks, and warehouse flooring. Generally, many industries customize the steel railings as per needs and shapes. Similarly, these steel railings can also be welded together at all once. The only concern is that these can cause physical loads and stress over the structure. But a railing should provide a support system and be light in weight compared to other building components. In this case, you can use steel tubes that are lower in weight, and their hollow shape offers a perfect strength-to-weight ratio. Steel tubes and MS chequered plate can be used in every residential and commercial industry.

Electrical trough:

If you take any electrical equipment that protects wires, cables, devices, and switches, they should be protected from damage. Especially if these equipment have to be placed near the condenser units, CCTV camera, and the electrical box, they are quite at risk. So, to prevent damage and safeguard the devices you need an electrical trough in the form of steel tubes to reroute and prevent them from moisture.

Thus, these are the ways in which steel tubes are used for various purposes. So, buy quality steel tubes from Bharat Steels, the best JSW steel dealers in Chennai, to ensure your building’s safety.
