In both the standards, there is four number which represents the type of steel. There are two major types of numbering systems used for differentiating the grades, the first is the American Iron & Steel Institute (AISI), and the second is the Society of Automotive Engineers (SAE).
There are many grades of steel which are classified according to their properties. Depending upon the application that will be used, one has to select the appropriate material for steel. These four types differ in many aspects such as their physical properties, its chemical composition, corrosion resistance, environmental properties etc. Depending upon the carbon content, steel is classified into various types – Due to this, iron becomes an Iron-carbon alloy which is called as steel. Carbon is added to reduce the iron oxide and releases carbon dioxide into the atmosphere. In smelting, the iron oxide has a lot of oxygen content in it. Limestone converts the unwanted impurities into a waste slag which can be removed easily and we can get molten iron.
So, in order to remove those impurities limestone is added while smelting. In this process, an iron ore gets converted into a molten state but it still contains impurities. This process is called a smelting process. Steel is produced by heating the iron ore in a blast furnace at a very high temperature. Due to adding carbon content, iron becomes strong and steel is made. But it can be made brittle by adding some alloy materials to it. Pure Iron is very soft and ductile in nature due to its less compact crystal structure of iron. The molten iron is then cast into the iron products. Iron is a metal that is extracted by melting the iron ore with the help of coal into the blast furnace. It is in the form of ore such as iron oxide also called hematite ore, magnetite ore, etc. Iron is commonly found deep inside the earth’s crust but it is not pure. Steel is used in many industries and has many applications due to its low cost and higher strength properties. Iron is extracted from the Iron ore with the help of various methods and steel is obtained after adding some alloy such as carbon into the extracted Iron which will provide high tensile strength to it. Steel is a metal which is an allotropic form of Iron with some alloy elements especially carbon and other materials. You can choose among different types of metals like Carbon Steel, Aluminum, Zinc, Copper, Brass, Tungsten, etc. This is a very handy calculator and you can customize it as per metal type, metal shape, and the number of pieces. After clicking on the Calculate button, the weight of metal is calculated immediately.Formula to calculate the weight of a metal varies according to metal shape, dimensions of metal piece and number of pieces.flat bar, sheet plate, ring, round bar, square, hexagon bar, round tubing, square tubing etc.) This calculator is useful to many design businesses related to the metal industry. Metal Weight Calculator is a simple calculator that calculates the weight of different metals.
