Three blocks of iron plus one block of carbon (coal) produces four blocks of steel bars.
Steel is one of the most useful raw materials in the game.
Steel in the real world
Making steel in the real world is a bit more complex than in BAW. While the main ingredients are indeed iron and - most often - carbon, other ingredients can be added to change the properties of the manufactured raw material. In regular steel about 98 percent is iron while up to 2 percent is carbon.
Other possible ingredients in steel include: manganese, nickel, chromium, molybdenum, boron, titanium, vanadium and niobium.
History of steel
Steel was known in antiquity, and may have been produced by managing bloomeries, or iron-smelting facilities, in which the bloom contained carbon.
The earliest known production of steel is a piece of ironware excavated from an archaeological site in Anatolia and is about 4,000 years old. High-carbon steel is known to have been produced in India from around 300 BC. This type of steel is called wootz or Damascus steel, and is known for its durability and ability to hold an edge.
The largest steel construction on Earth is the National Stadium in Beijing, China also known as the “Bird’s Nest”. The stadium was built for the 2008 Olympic Games in Beijing. 110,000 tons of steel was used in the construction.
Steel is one of the most recycled materials in the world. It is cheaper than making new steel from iron, and steel doesn’t lose any of its inherent physical properties during the recycling process.
