It is known that steel is widely used in many different areas, and it contains all kinds of different types. Generally, depending on the cross sectional shape, the steel can be divided into four main categories of profiles, steel sheets, steel tubes, and metal products. Of course, every big category can own several different small categories, and the related steel prices is not the same. Most the processing of steel belongs to pressure processing, which can make steel produce plastic deformation. According to the processing temperature of steel can be divided into two kinds of cold and hot processing.
Steel is an iron-carbon alloy which contains carbon between 0.04%-2.3%. The chemical composition of steel is so different, if the steel can only contain carbon steel known as carbon steel, in the actual production, in order to ensure its toughness and ductility, the carbon content is generally not more than 1.7%. And the main elements of steel except iron and carbon, it contains silicon, manganese, sulfur, phosphorus, etc.
The next, there are some introductions about several normal steel products, including steel plate, steel coil, galvanized steel,
steel pipe, etc.
Steel Plate
Steel plate is with molten steel pouring and pressed flat-shaped steel after cooling. According to different rolling ways, steel plate can be divided into hot-rolled and cold-rolled. Generally, steel plate can used as bridge plate, boiler plate, automobile manufacturing plate, etc. And hot rolled steel plate is a very big application in the industry, which is produced by hot rolling.
Steel Coil
Steel coil, is also known as rolled steel, which is can be produced by steel hot or cold pressing. In order to facilitate storage and transport, steel coil usually can be processed plate or strip, etc. Steel coil is divided into hot rolled coil and cold rolled coil, and the hot rolled coil is processing products which is in the front of the billet recrystallization, and cold rolled is subsequent processing after hot-rolled-coil. In order to enhance the resistance to corrosion of steel, you can use galvanized steel coil.
Steel Pipe
Steel pipe can be divided into two categories, including seamless pipe and welded steel pipe. Usually, seamless pipes are made of high quality carbon steel and use two different ways to produce: hot rolled and cold rolled. Welded steel pipe is rolled into a tubular steel plate on the seam or spiral seam welded. Weld steel pipes can be used for water pipelines, gas pipes, heating pipes, electrical pipes, etc.
