Investigating the Behavior and Properties of Various Steels

Based on an old definition, steels are alloys of iron and carbon in which the amount of carbon varies up to ۱.۷% and elements such as manganese, silicon in amounts less than ۱% and phosphorus and sulfur in small amounts as well as elements Like chromium, nickel and molybdenum exist as alloying 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. Their tensile strength varies from ۴۰۰ to ۲۰۰۰. Simple carbon steels are steeling 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 such as 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 in its pure form, is found in nature as iron ore, which is hard and brittle. The tendency of iron to combine with other elements, especially carbon, which has a great effect on its hardness, brittleness and brittleness.
