STEEL
ONE MATERIAL , MANY SOLUTIONS !
The human civilization stage reached at the present moment is related to the science progress in the study of metals .
Since ancient times , starting the Bronze Age , metal had an important role in the life of human communities , helping the development of the society . From the ancient world seven metals : gold , copper , silver , lead , tin , iron and mercury , science has progressed enormously , reaching special alloys like uranium , plutonium on a sacrifices sprinkled road .
To understand the need for metals and to discover their world we have to look around us and realize that some things around us are made of metal whose discovery , obtaining and processing include the efforts of tens of thousands of people .
One of the current civilization indispensable metal is steel , an alloy of iron and carbon whose percentage is between 0,018 % and 2.04 %.
How would the world be without steel ? Well , perhaps we would never have reached the present level of development and many things would have remained unknown , many would have remained undiscovered .
Steel is the material most widely used in industry . the railroad tracks , major components of aircrafts , tools , knives and many other things that may at first seem trivial led the world to the present moment and to the actual development stage .
There are simple things without which we could not eat or travel to every corner of the world , we could not enjoy life like we do now .
So , can we imagine the world without steel ? Andreea Sandu
