There's a good chance that steel is on the list if you list down all the things on earth that you're grateful for. For many years, steel has actually been defined as a step up in civilization, from bone weapons to steel swords that cut and slash better. Now, take a step back to see the one thing you need to really be grateful for: iron.
As simple as it is, steel can’t be created without iron ore, the second most abundant ore in the world. The ore the ancients called "ferrum" helped empires and cities to progress not just in regards to military capabilities, but also in economy. Iron will forever be an important part in steel fabrication in Melbourne and all over the world. Nevertheless, in spite of steel's durability, a closer look at iron exposes that it isn't as strong as it appears.
For something that produces a strong product such as steel, iron is more brittle than a typical rock. While it may not fit the robust profile steel holds, the brittleness of iron ore assists miners to gather the ore easier and in larger quantities, keeping iron products inexpensive. Its transformation from a breakable ore to a sturdy product is nothing short of a Cinderella tale.
The impurities of iron ore is the cause of its brittleness, namely the traces of carbon. To make the end product hard, the process gets rid of the impurities from the ore, which are smelted. As normal iron has more than 2 percent carbon, its final products have constant carbon concentrations of around 1.5 percent.
To create a stronger steel, other metals such as zinc and copper are included in particular quantities. Some metals could also make steel more resistant to corrosion compared with regular steel; this is finest for structures that require the most from their steel frames. The combination of heat and other metals completely transforms normal iron ore to something humanity can use in many ways. The human race absolutely has iron ore to thank for.
