USA HISTORY

Detailed explanation-1: -The Bessemer process allowed steel to be produced without fuel, using the impurities of the iron to create the necessary heat. This drastically reduced the costs of steel production, but raw materials with the required characteristics could be difficult to find.

Detailed explanation-2: -What is the most commonly used metal in the world? Steel is the most commonly used metal in the world today, widely used by the building industry. An alloy of iron and other elements, steel has the benefits of high tensile strength combined with low cost which make it perfect for use in construction.

Detailed explanation-3: -All steel types are iron alloys with the addition of different elements. They are always primarily composed of iron and carbon, with a carbon content of 2% or less. They also contain 1% manganese and small amounts of other elements. Most steel alloys are manufactured using iron ore, scrap steel, coal, and limestone.

Detailed explanation-4: -There are three main raw materials needed to make steel. Iron ore, coal and scrap steel.
