Rolled Steel and Its Classification
Rolled steel is a material that has been produced through a process of rolling, which is a method of shaping metal into different parts. In this process, metal is passed between two rolls, which create an even surface. This process was first developed in the early 19th century and has since been used to produce many types of metal products, including components for vehicles and ships.
Steel is an alloy of iron and carbon with other elements in varying amounts and is the most commonly used material in manufacturing. Steel products are made through the process of rolling, which uses powerful machinery to press the steel into different shapes. It is important to note that each type of steel will respond differently to the rolling process, depending on its intended application.
The variety of rolled steel products can be classified according to the type of shape they take on, the degree of thickness of the metal, the temper of the material, and its surface texture. Depending on the intended purpose of the product, there are various types of rolled steel products available in the market.
The most commonly used type of rolled steel is hot rolled steel, which is made by heating the steel and rolling it into the desired shape. Hot rolled steel has a rough surface and is typically used in industry and manufacturing applications, such as the automobile industry. This type of steel is extremely durable, making it an excellent choice for the construction of roads, bridges, and other structures. Hot rolled steel is also one of the most affordable varieties available in the market.
On the other hand, cold rolled steel is made through a different process. In cold rolling, the steel is heated to a much lower temperature and then passed through a set of rollers to create its shape. This process creates a much smoother surface, which makes it perfect for painting, stamping, and other types of finishes. Cold rolled steel is often used in the production of beaten hardware and structural components, as well as for furniture, fixtures, and appliances.
Another type of rolled steel is galvanized steel, which is composed of zinc and iron. It is made by running the steel through a bath of zinc, giving it an initial layer of rust-resistant protection. Galvanized steel is used in a variety of industries as it is highly resistant to corrosion, making it great for outdoor projects such as fences and residential roofs. Galvanizing is also extremely economical and is commonly seen in everyday household items such as kitchen sinks, playground equipment, and garage doors.
Finally, we have stainless steel, which is non-corrosive, making it one of the most desired materials for food-grade products. Stainless steel is extremely durable and will not be affected by acidic foods, which makes it ideal for use in restaurant kitchens and sanitary equipment. Not only is it highly resistant to corrosion, but stainless steel also has a beautiful silver finish that adds an aesthetic appeal to any product.
In conclusion, rolled steel is a popular material used in both the industrial and consumer manufacturing industries. It is available in a variety of forms, each suited for a different purpose, and is an incredibly versatile material. Whether you need a durable product for a tough job, or a beautiful finish that adds a touch of elegance, rolled steel can be the perfect solution.
