Application of steel in industries

Application of steel in industries

Steel is one of the most widely used metals in the world, which has different characteristics in different shapes and alloys to meet a wide range of applications. Steel in its simplest form is iron alloyed with carbon, but a series of steels with different properties can be created by adding other elements such as chromium, nickel, molybdenum, silicon and manganese. Due to its diverse properties, high strength and low production cost, steel is used to produce many products, and it is not surprising that many industries depend on steel. Without the steel industry, many other industries would not have grown as much or flourished as they do today.

Steel in industries

Due to its unique properties, steel in industries. Industries such as; Interior and exterior decoration, medical industries, marine industries, electronic industries, jewelry making and jewelry manufacturing, transportation and automobile manufacturing industries, kitchen and household appliance production, food industries, electricity production industries, agriculture, industrial equipment and machinery manufacturing, furniture production and Interior decoration, oil and gas industries, mining industries, construction are some of the most important industries in which steel is used. But in general, steel applications can be divided into seven basic parts based on the amount of consumption. According to the report of the World Steel Association (WSA), the percentage of steel allocated to each sector is as follows:

  • Buildings and infrastructure 51%
  • Mechanical equipment 15%
  • Car 12%
  • Metal and medical products 11%
  • Shipping 5%
  • Household appliances 3%
  • Electrical equipment 3%

Steel in building and infrastructure

More than half of the annual steel production is used to construct buildings and infrastructure such as bridges. According to WSA, most of the steel used in this sector is in reinforcing bars (44%) and sheet products such as sheets used in interior walls and ceilings (31%). and structural sections (25%) are used. In addition to structural applications, steel is also used in buildings for HVAC systems and in things like stairs, rails, and shelving. Different types of steel can be designed to meet the unique needs of infrastructure projects to be used in different components in a variety of environments. Depending on the conditions the structure is exposed to, a specific steel alloy or a more common alloy can be used.

Steel In Construction

In addition to bridges, steel applications in transportation-related infrastructure include tunnels, rail tracks, fuel stations, train stations, ports, and airports. According to WSA, approximately 60% of steel is used in this sector. As a rebar, it is a toothed steel rebar that is placed inside the reinforced concrete. Steel is also widely used in utility infrastructure, including for fuel, water and electricity. WSA states that half of the steel used for utility infrastructure is in the form of underground pipes for water or natural gas. In the construction industry, a stable material like steel allows structures to be built quickly and at low cost. Since steel is produced in various alloys and shapes, it can meet the needs of any project.

The importance of steel in the construction industry

Steel can even be alloyed in various ways to protect against the elements. These characteristics of steel allow it to be used in almost any type of environment in the infrastructure of a building. The beginning of the 20th century saw the development of more efficient techniques for steel production. These developments have led to the rise of tall buildings as well as the growth of railways around the world. In fact, many famous historical structures, such as the Empire State Building, owe their strength and longevity to steel as their primary construction material. The construction industry continues to look to steel to provide solutions to the infrastructure needs of developing countries.

Steel in mechanical equipment

Steel is one of the most important and widely used materials in mechanical equipment. Steel is actually an alloy of iron and carbon, whose mechanical and chemical properties are improved by adding other elements such as chromium, nickel, molybdenum and vanadium. Even if a product is not made of steel, it is most likely produced by a steel machine. The second major use of steel includes bulldozers, tractors, machinery for making auto parts, cranes, and hand tools such as hammers and shovels. Also, rolling mills are used to shape steel in different shapes and thicknesses.

Steel is used in the manufacture of machine parts due to its high mechanical properties, resistance to corrosion and oxidation, formability and welding power. This includes parts such as nuts, bolts and industrial screws, rotating machine parts and cutting tools. Also, steel is used as the main material in the production of cutting tools and precision tools. For example, knives, cutting plates, cutting discs and precision tools are produced from steel. Due to its high corrosion resistance, hardness and ability to withstand mechanical stress, steel is an ideal choice for cutting tools that deal with hard and resistant materials.

Steel in the car

Steel is widely used in the automotive industry. Among the uses of steel in this industry, we can mention the manufacture of engine parts, car body, beams and other metal parts. Steel is a good choice for car parts due to its high impact resistance, flexibility and stability against different environmental conditions.

Steel In Automobile Manufacturing

According to the WSA, on average, approximately 2,000 pounds, or 900 kilograms, of steel is used to build a car, with about a third of that used in the body structure and exterior, including the doors. Different types of steel are used in different parts of the car such as body, doors, steering wheel, wheel axle, interior, suspension system, gearbox and engine. Advanced high-strength steels, which are made using complex processes and are lighter in weight than traditional steels, make up about 60% of the body structure of modern cars. Today, most cars and other vehicles use advanced high strength steels or AHSS

Steel in metal and medical products

This section includes various consumer products such as furniture, food and beverage packaging, and razors. Steel is a valuable material in the packaging industry because it can protect your goods from the elements such as air, water and exposure to light. Steel is also fully recyclable, which can reduce production costs and help the environment. Steel is used in medical equipment as a very important and practical structural material. Among the types of steel used in medical equipment, L316 stainless steel can be mentioned. This type of steel is one of the most resistant and high-quality steels, and some of its features are:

Steel is an ideal material for marine applications because it can resist rust better than other common shipbuilding metals such as bronze, galvanized steel or brass. Steel is important for maritime transport in another way: almost all of the world’s 17 million shipping containers are made of steel. Chemical tankers often represent the greatest applications of steel, as these tankers require a material that is easy to fabricate, capable of being thoroughly cleaned when changing cargo, and highly durable. In addition, steel is found in trains in wheels, axles, bearings, and engines. In airplanes, steel is very important for engines and landing gear.

Steel is widely used in the aerospace industry due to its features such as light weight, high resistance to heat and pressure, corrosion resistance and strong mechanical properties. Steel is used in the construction of various parts, including engine parts, turbine systems, spacecraft and satellite bodies. As a strong structural and metallic material, steel is very suitable for enduring the harsh conditions of space and avoiding risks such as thermal contraction and high temperature changes.
