Steel : Steel is an alloy primarily comprises of Iron (Fe), Carbon (C), Manganese (Mn), Silicon (Si), with other element serves as a secondary composite. Steel is a material which cannot be found in nature, but it is manmade (and machine) and it is based on the process of improving Iron (Fe) to obtained better properties in terms of strength, ductility, machinability, hardness, toughness, durability and nature resistance.

Iron : Scientific symbol Fe, Iron is a metal that exist in nature in the form of Iron Ore. It’s mainly silvery gray to black in color and is mostly magnetic in nature. It is found abundantly in the earth crust especially in the highland and mountainous area in the form of iron ore along with other types of metal. Iron ore must be purified using a smelting process (liquefying iron ore and remove impurity by using high heat) and turned into iron before it can be used.
