According to an old definition, steels are alloys of iron and carbon in which the amount of carbon varies up to 1.7% and elements such as manganese, silicon in amounts less than 1%, and phosphorus and sulfur in small amounts, and also there are elements as alloy elements. Having high strength and good flexibility distinguishes steels from other alloys and non-metallic materials, and steels are very resistant to variable actions and impacts. Simple carbon steels are steels whose alloy percentage is very small. These types of steels have the highest amount of consumption in all types of steels. These steels are divided into three categories, which are explained in the next sheet. Due to the wide use of iron alloys (cast iron and steel) in the industry, we can understand the importance of this goal in human life. Iron, which is a very soft and flexible element, is found in nature as iron ore, which is hard and brittle and it has the tendency is to be combined with other elements, especially carbon. Steel is the most widely used and recycled metal material on earth. From high-temperature stainless steels to plain carbon products, these carbon steels in various forms and alloys offer various properties to meet a wide range of applications. Likewise, because of the combination of the properties of this metal of high strength and relatively low production cost, this widely used metal material is now used in countless products.
