Scott Hawkins. Re: What is the density of steel? MadSci Network. 11 September 1997. "The short answer to your question is that the density of plain mild steel is 7.85. The long answer is that depending on where you look, or the grade of steel that you are talking about can change this value. A density of 7.88 is often quoted for mild steel as well. If you add alloying elements such as tungsten, chrome or manganese to improve the steel, the density will change. So the long answer is that the density of steel can vary between 7.75 and 8.05." 7.75–8.05 g/cm3

A man of steel is what every girl wants and what every guy wants to be. Steel is like air, it's everywhere: from bridges to fridges and from washing machines to canteens. Steel is mostly composed of iron and carbon. It contains small amounts of manganese and even smaller amounts of silicon, phosphorous, oxygen, sulfur, and other elements. Henry Bessemer created the Bessemer process in 1856 to manufacture steel cheaply.

Density is one of the numerous properties of steel. It is calculated by dividing the mass by the volume. Steel comes in many different forms. Their densities differ by type (see tables below).

There are many uses for steel. Stainless steel, for example, is used for surgical tools and kitchen utensils. It is a type of steel that contains low carbon levels and at least 10.5% of chromium. This results in corrosion resistance. Another kind of steel, tool steel, is used for metal cutting tools an drill bits because it is hard, but brittle. The amount of carbon in carbon steel determines the hardness of the steel. The more carbon it contains, the harder the steel. Carbon steel is often used for automobile parts.

Steel and its various forms have multiple uses around the world. The nature of the steel depends on its content, which results in varying densities. In most cases, the denser the steel, the harder it is. Hence, a man of steel is every girl's dream.
