What is steel

-A A +A

Steel is an alloy of iron with a carbon content that can range from 0.03% to 1,075% of its composition, depending on its grade.

Steel is not the same as iron and they should not be confused. Iron is a metal relatively hard and tough, with atomic diameter (dA), 2.48 Å  with melting temperature of 1535 ° C and boiling point 2740 ° C.

The main difference between iron and steel lies in the carbon content: steel is iron with a carbon content between 0.03% and 1,075%.

Steel retains the metal characteristics of iron in its purest form, but the addition of carbon and other elements either metallic or non-metallic improves its physical-chemical properties, especially its resistance.

There are many types of steel according to the content of alloying elements. Each type of steel will allow different uses and applications, making it a versatile and widely used material in modern life.

The two main components of steel are abundant in nature: Steel can be recycled indefinitely without losing their attributes Those facts facilitates its production on large scale. Its variety and availability makes it suitable for numerous uses as the construction of machinery, tools, buildings and public works, aeronautics, automotive, medical equipment  etc. contributing to the technological development of industrialized societies, as no material can match it on resistance to impact or fatigue.
