Ferrous alloys are metals that primarily consist of iron and are known for their strength and durability. They are widely used in construction, manufacturing, and various industrial applications due to their excellent mechanical properties. Common examples include carbon steel and stainless steel, which are essential in building infrastructure and producing everyday items. These alloys can be further categorized based on their composition and properties. For instance, alloy steels contain additional elements like manganese or chromium to enhance specific characteristics. The versatility of ferrous alloys makes them a cornerstone of modern engineering and technology.
