Learn About Three Kinds Of Metal Finishes & Its Properties

October 21, 2023

In simple terms, metal finishing is the application of a specific layer or coating to a metal’s surface or an industrial process that prepares the metal’s outer surface for further processing. Various metal finishing methods blend chemical, mechanical, and electrical techniques to attain the desired outcome. This blog explores the three different types of metal finishes.

Metal Electroplating:

The advantage of applying metal electro-plating is to make the surface remain consistent. This procedure improves the metal’s resistance against corrosion, enhances its surface, and minimizes friction when it reacts with other metals. The common metals used for electroplating despite and its ferrous and non-ferrous properties are copper, gold, zinc, chromium, and tin.

Electroplating is one of the preferred metal finishes by JSW dealers, where the plating metal is immersed, dissolved, and applied to the metal’s surface that needs to be coated. It comprises four key elements: anode, cathode, electrolyte, and continuous electrical current. Anode denotes the metal responsible for coating, and the metal needed to be coated is placed on the cathode. This entire procedure occurs within a solution where the anode and cathode are immersed, serving as the conduit for the electricity flow.

Metal Polishing:

Similar to other metal finishing techniques, polishing aims to eliminate imperfections found on the surface of the metal. The choice of abrasives employed in the polishing process varies depending on the initial state and condition of the metal and is categorized as bonded, loose media, or coated. The initial polishing stage involves using rougher abrasives to smoothen the deformities. At the same time, finer or smoother abrasives are employed for polishing.

In addition to the metal’s condition, the metal type influences the choice of abrasives for polishing equipment. This choice is primarily determined by the metal’s tensile strength, enhancing its capacity to withstand maximum loads before breaking. Metals with low tensile strength, such as copper, aluminum, or brass, typically utilize abrasives of silicon oxide. Conversely, high-tensile strength metals like iron, steel SAIL TMT bar and carbon require white or gray aluminum oxides. These abrasive materials are further polished with cloth, rubber, cotton, and similar other materials.

Metal Blasting:

It is also known as abrasive or sandblasting. This procedure utilizes high-powered equipment to release abrasive materials. Like polishing, the aim is to refine rough surfaces and eliminate metal defects. In contrast to polishing, gentler abrasives are favored over coarser ones, resulting in a matte-like texture for the finished product, such as in MS chequered plate.

Various subcategories within the field of blasting, such as shot peening, enhance a range of metal properties, including its resistance to cracking and stress corrosion. Various applications and methods are available for enhancing the qualities of metals and alloys, such as aesthetics and functionality. Selecting the suitable metal finishing process should be done with consideration of the metal. When this principle is applied with the appropriate materials, manufacturers can incorporate metal finishing into their fabrication procedures to gain maximum advantage.

Fabrication Of Steel And Its Various Applications

April 21, 2022

Fabrication of steel is a technique of creating a variety of components and items that we utilise on a daily basis. It’s a method of converting raw steel into a set of items that can be used in building projects. This procedure entails taking crude ingredients and forming them into the desired shape. You can contact bharat steel suppliers in Chennai for high-quality steel supplies.

The natural resources are cooled down and converted into completed steel products before being formed into various shapes in this manner. Steel production necessitates highly skilled personnel with prior expertise converting raw materials into marketable products.

The application of steel fabrication is determined by the end-use of the produced product. However, steel fabrication falls into three main categories,

Structural fabrication

Metalworking that is employed as part of the construction process is referred to as structural fabrication. Typically, stores, manufacturers, buildings, and skyscrapers use structural manufactured steels purchased from reputable steel dealers in Chennai.

Commercial fabrication

Fabrication for Business technique creates consumer-oriented commercial products. The greatest examples of businesses manufacturing are appliances and automobiles, as well as steel parts.

Industrial fabrication

Fabrication in the workplace creates components that are employed in the development of other machinery. The greatest examples of workplace fabrication are bandsaws and iron working machines.

Steel manufacturing process

Steel’s main features include stiffness, resistance to corrosion, and longevity. Punching, folding, cutting, machining, stamping, shearing, welding, and casting are the most common ways for producing steel. You can rely on steel suppliers to get it done according to your necessity. Here’s a quick rundown of how each of these steps works:

Punching

Punching is indeed the process of making an opening in a metal piece by placing it under a die and drilling it through. To fasten the latches on each other, wells are created into a plate of steel in most situations.

Folding

Folding requires manipulating steel into a certain shape and is one among the most challenging tasks. In this method, the steel panels are pleated at a right angle or at various degrees to make the product somewhat blunt.

Cutting

Dividing the steel plate into halves, thirds, or smaller parts is the most often used steel production method. Typically, the sheets or bars are chopped and reshaped into new shapes. Laser beams and fusion flames are used to cut them, resulting in a more complicated and high-tech sculpture.

Machining

This is the process of dismantling the parts of a metal object. The procedure is commonly carried out on a lathe, which revolves the steel along equipment which trim the rough edges to shape the item.

Stamping

This is a fabrication method for forming plain metal pieces into specific forms. It’s a sophisticated procedure that includes blanking, punching, bending, and piercing, among other metal forming techniques.

Shearing

This is a metal fabrication technique that involves cutting alignments on a plain steel plate. An upper blade and a lower blade are built near with a little gap between them during this procedure. The blades are normally fixed. Shearing of steel can be done on layers, strips, bars, plates, and even angular metal stock.

Welding

This process involves the joining of two separate metal parts. The parts used in this process include sheet, panels, bars or any other shaped steel. They are joined together through numerous methods and machines that result in finished usable products.

Casting

Casting is a method of pouring molten metal into a mould that contains a hollow cutout of the required shape. After the molten metal has solidified, it is taken from the furnace, showing the finished result, also known as the “Lay up Form.” Casting is appropriate for a wide range of intricate shape-making since it is one of the most adaptive ways of metal fabrication. Jewellery, sculptures, and weaponry are some of the most common examples. Steel is utilised in a variety of applications, from staplers to plane parts. It comes in a variety of grades with different chemical compositions. At Bharat Steels, we give you high-quality steel that is long-lasting and reliable.

Different Types Of Metal Fabrication

Every building or structure that you see today is nothing without steel. Steel is one of the essential construction materials that stands stable for the years to come. But have you ever thought about how steel is fabricated into the desired shape before reaching your hands? Hardly, right? However, the steel we use as tubes and pipes undergoes various fabrication processes to meet the construction requirements. So, we can say that metal fabrication is a process where the raw materials are created into desired structures by various processes. The steel suppliers in Chennai consider the different types of metal fabrication as a value-added process because it is where they are created, developed, and assembled. So, the metal fabricators work with a wide range of raw materials which includes plate metal, welding cast metal, wires, and rods. Thus, let us see the various processes involved in fabricating steel and other metal products.

Cutting:

The foremost process involved in metal fabrication is cutting. You can say that the cutting process is one of the earliest fabrication processes and most of the MS steel suppliers in Chennai follow this method. So, typically a cutting process is used to cut the unwanted pieces despite being a ferrous or non-ferrous metal. The cutting process can include machines from basic to complex. The metal fabricators name these final metal products depending on their cuts. The cutting tools involved in the metal cutting process are backsaw, hacksaw, and coping saw. Similarly, sometimes for complex metal fabrication, metal fabricators use power tools like drilling and grinding.

Metal stamping:

Next, a popular metal fabrication process is metal stamping. This process is more beneficial if the raw material is in the sheet format. So, the process involves transforming the flat sheets into desired shapes. These metal sheets are punched, bent, and pierced to obtain a specific shape. These stamping processes are ideal for metals, like carbon steel, stainless steel, aluminium, bronze, MS chequered plate, and various alloys. Thus, metal stamping finds its application in the automotive industry to design components like wheel hubcaps, trunk lids, firewalls, doors, and other vehicle-related parts. Another reason why metal stamping is used in the automotive industry is to customize the design as per the client’s requirements.

Welding:

Thirdly, steels surely undergo the welding process because of high usability. Welding is a fabrication process where two or more steel or metal parts are joined together under high heat and pressure. This process includes equipment like shielding gas, consumable and non-consumable electrodes, fillers, flux, and welding machines. As there are various welding techniques involved and the most common methods are Gas Tungsten Arc Welding, stick welding, and Gas Metal Arc Welding (GMAW).
