Iron is a pure metallic element, while steel is an alloy made primarily of iron combined with carbon and sometimes other elements.
Steel is an alloy composed of elements like carbon and iron. Iron is an element found in the Earth’s crust. Iron is actually the base metal found in steel. This contributes to steel’s overall strength. While wrought iron and cast iron were the material of choice in ancient times, they...

WHAT IS ALLOY STEEL? In addition to iron and carbon, an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel is called alloy steel. According to the different added elements and appropriate processing technology,alloy ste...
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements.Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, ti...
he ended up obtaining a corrosion resistant metal alloy, and added chrome to the cast iron. The invention found applications in almost all industrial sectors including for the production of cutlery, health equipment, kitchens, automotive parts, and more, replacing traditional materials such as carbon...
