Steel and iron are two of the most common materials used in the manufacturing industry. They are used to make a wide range of products and components. Although iron and steel look similar, they are two unique materials with their own characteristics and qualities.
What is Iron?
Iron is a lustrous, ductile metal with atomic number 26. It has a chrome appearance that reflects a significant amount of light. Iron is also a ferromagnetic metal, which means that it is magnetic and attracts other ferromagnetic metals.
It is important to note that iron is an essential mineral. Like vitamins, essential minerals are necessary for proper nutrition. When consumed, iron provides the human body with the nutrients necessary for the production of hemoglobin. The mineral essentially acts as a catalyst for the production of hemoglobin, which is one of the main components of red blood cells. If you don't consume enough iron in your diet, your body will not be able to produce enough red blood cells, resulting in a medical condition known as iron deficiency anemia. Food sources rich in iron include beef, chicken, oysters, beans, lentils, fish, legumes, bread and fortified cereals.
What is steel?
Steel, on the other hand, is a ferrous alloy composed primarily of iron and carbon. Many people assume that steel is a metal, but this is not necessarily true. Although it exhibits similar properties to metals, it is technically classified as an alloy. Metals occur naturally as an element, while alloys consist of various mixed elements and components that are not found naturally as an element. You can find iron naturally as an element. In fact, it is the most abundant element on Earth. But you won't find steel anywhere in Earth's outer or inner core, as it's a man-made alloy that requires mixing iron and carbon.
All steel contains iron, but it also contains carbon. The addition of carbon is what distinguishes iron from steel. By weight, steel contains about 2.14% carbon. Although it is a relatively small amount of carbon, it results in significant physical changes. Steel, for example, is harder and more resistant than pure iron. And unlike iron, steel is not an essential mineral. You don't need to consume steel as part of your diet.
The main difference between iron and steel is that the former is a metal while the latter is an alloy. Iron is simply a naturally occurring metallic element on Earth. In comparison, steel is an artificial alloy made by mixing iron and carbon.
