Iron (Fe), chemical element and one of the transition elements, the most-used and cheapest metal. Iron makes up 5 percent of Earth's crust and is second in abundance to aluminum among the metals. Iron, which is the chief constituent of Earth's core, is the most abundant element in Earth as a whole.

What is steel made of? Steel is made of an alloy of iron and carbon in which the carbon content ranges up to 2 percent (with higher carbon content, the material is defined as cast iron). Iron, the major elemental component of steel, is one of the most plentiful elements in the earth's crust. All steel alloys are primarily iron and 0.002–2.1 ...
Details
Hot roll steel is made by heating slabs of steel to approximately 2,300 degrees Fahrenheit. Upon transfer from the furnace and cooling, the material is then high-pressure washed to remove any mill scale formed when the hot material met the air. Finally, the material is treated with cooling sprays before entering coolers.
Details
Steelmaking is the crucial stage where molten iron obtained from ironmaking is transformed into steel with specific properties. The most common method used is the basic oxygen steelmaking (BOS) process. In this process, the molten iron is transferred to a converter, and high-purity oxygen is blown through it. The oxygen reacts with impurities ...

Steel is a discovery of the Iron Age, a period that started around 1200 BCE. Iron ore was first mined in Central Asia and Europe, and humans at this time used iron to make tools and weapons in a practice called ferrous metallurgy. Iron products evolved during this time, beginning with blacksmiths producing wrought iron goods.
Details
Steel - Production, Uses, Types: The steel industry has grown from ancient times, when a few men may have operated, periodically, a small furnace producing 10 kilograms, to the modern integrated iron- and steelworks, with annual steel production of about 1 million tons. The largest commercial steelmaking enterprise, Nippon Steel in …

Steel is an alloy of iron and carbon that has been heat-treated to improve its strength and toughness. The carbon content in steel typically ranges from .2% to 2.1% by weight, which influences its properties, such as hardness and ductility. Steel finds extensive use in construction, manufacturing, automotive, infrastructure, and many other ...

A blast furnace is a steel cylinder lined with refractory. It operates continuously until the lining wears out, which takes many years to occur. The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400º to 2100ºF. Molten iron is produced in a blast furnace by the following steps: 1.
Details
The Steel Manufacturing Process. The steel production process is a multi-faceted journey that begins with extracting and processing iron ore, a primary raw material essential to steel making. Iron ore undergoes a series of refining steps to extract the iron content, culminating in the creation of molten iron. This molten iron is then subjected ...
Details
What is Iron Ore Used For? The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
Details
Steel is made out of alloy products, pig iron or iron ore and carbon, and usually contains up to 2% of carbon content which is moved through the refining process. Steel with a higher carbon content is called cast iron. Other alloying elements like manganese, chromium, copper, nickel, titanium, molybdenum, tungsten, and vanadium …
Details
This innovation meant that, finally, iron ore from anywhere in the world could be used to make steel. Not surprisingly, steel production costs began decreasing significantly. Prices for steel rail dropped more than 80% between 1867 and 1884, as a result of the new steel producing techniques, initiating the growth of the world steel …
Details
How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

The table below provides a comparison of their differences. Iron and steel carbon content table. Iron with a carbon content less than 0.02% is referred to as wrought iron, while iron with a carbon content between 2.11% to 4.3% is called pig iron. Steel falls in between these two categories. The carbon content impacts the performance of iron.

Coke and iron. About 70 percent of steel today is made how it's always been made: in giant, extremely hot furnaces. Purified coal, or "coke," is heated and melted with iron oxide and limestone, then injected with oxygen to reduce the carbon content of the mixture and to remove impurities.

Most steel in South Africa is produced via two basic routes: The Blast Furnace-Basic Oxygen Furnace (BF-BOF) route and the Electric Arc Furnace route (EAF). Blast furnaces produce iron from iron ore. In a second step a basic oxygen converter turns iron, with some additions of scrap, into steel. Electric Arc Furnaces and Induction …
Details
The main difference between iron and steel is that the former is a naturally occurring element, while the latter is an alloy of iron and carbon — something that doesn't naturally occur. Steel is stronger than iron in the domains of yield and tensile strength, but it's also significantly tougher.
Details
It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal. By 1920, nearly 90% of US steel was produced using coke.
