Conventional steels, not produced through powder metallurgy, are among the most widely used materials in industry due to their combination of mechanical strength, ductility, and versatility. These steels, which include carbon alloys and alloy steels, have been developed over centuries and have undergone continuous improvements thanks to research and technological innovations. Today, conventional steels are used in a wide range of applications such as construction, automotive, tooling, and structural production, where the ability to withstand mechanical stresses, as well as machinability, is key. While they do not offer the advanced properties of alloys produced through powder metallurgy, conventional steels continue to be the preferred choice for many applications due to their cost-performance ratio.
