Steel is primarily an alloy composed of iron with usually only a small fraction of carbon in it to increase its hardness and durability as compared to other metals. The other components may be included or not. Common stainless steels which are somewhat less corrosion- and rust-resistant require an extra 11% iron.<br><br><br>Because the alloy composition of the steel consists mostly of iron, it is used in everything from sheets, plates and rods to nails and screws. It is also used for building ships, skyscrapers and automobiles. Steel has many beneficial characteristics which make it ideal for construction and other applications. One of the most important characteristics of the material is its extreme ductility; which means that it is highly elastic but also highly durable and strong.<br><br><br>Another benefit of the material is its high rate of temperature resistance. Temperatures below approximately 600 degrees are too hard to forge iron so engineers make steel by adding another layer of alloy steel to the bottom layer of iron to achieve the same strength. This second layer is referred to as cast steel or cold rolled steel. Cast steels are commonly used in building and construction because of their ductility, low density and high rate of temperature resistance.<br><br><br>Steel is made from a variety of alloys including carbon and ferrous alloys. Carbon alloys are composed of carbon, hydrogen, oxygen and nitrogen and are more commonly known as steel. Ferrous alloys consist of beryllium, cobalt, chromium and zinc and are often called by the names carbon steel, brass tubing or by the name carbide steel.<br><br><br>The composition of the alloy depends on the elements that compose the other elements. If you were to take a sheet of steel and rub your hands together, you would be able to feel the carbon atoms pressed together at the points where two sheets touch each other. When you compare this with a sheet of iron which has a similar composition the carbon atoms have a much bigger effect.

This is why steel is often referred to as a soft metal.<br><br><br>Because of the way that carbon steels contain fewer carbon atoms than iron, they can be brittle and are at a much higher risk of fracture. However, this feature is also what makes them extremely useful in a number of ways. Since steel is inherently less brittle than iron, it is often used to reinforce structures, such as the frame of a building. Since it contains low levels of carbon, it is also easy to repair damages in steel compared to iron, making it an environmentally friendly choice.<br><br><br>In addition to their strength and durability, another advantage to choosing steels over cast iron is their great all round properties. Steel is a ductile material and because of the great hardness it offers, it is considered to be very flexible. It is also resistant to a great number of stresses, including stress from tension and thermal expansion. Because of these properties, steel has been cast as an all round alternative to cast iron, but its high cost relative to iron means that many engineers still prefer the use of steels for a variety of projects. Cast iron is not as malleable and can crack when exposed to certain temperatures or pressure. As well as this, cast iron has a tendency to lose its shape when stressed, meaning that it must always be heated or cooled in order to regain its original shape.<br><br><br>There are a number of alloys available, but the two most commonly used in modern day steel production are iron and steel. The reason for this is that steel is extremely versatile as well as strong, while iron is a more traditional material that offers a limited variety of properties. Whatever your requirements, steel and iron are a great choice.<br>' |
