Steel is a highly durable and strong metal that is an alloy of iron and carbon. These two materials are put together because of their high tensile strength that make the resulting steel stronger than either carbon or iron. Carbon is used to stabilize and strengthen the steel by helping to harden the lattice of iron atoms.
Though steel is a metal that is used across the world now, it is not a new method or a new metal. Steel was first made in ancient time created with the help of bloomeries and crucibles that can be used in smaller areas. The earliest instance of steel that has been recorded dates back to almost 4,000 years ago in 1800 BC. Steel weapons from this period have been found and are the result of the early work of iron and steel smelters.
Steel was also produced in large quantities in Sparta and Damascus. The first instance of high carbon steel, similar to what we use today, was found in the Indian Subcontinent where it was then exported globally. As steel progressed, new methods of smelting emerged and made the process easier than ever before. Modern steelmaking starts with the same beginning process as the early steelmakers used.
Steel must be first smelted into what is called pig iron in a blast furnace. Early methods used charcoal while current methods use a compound called coke which is cheaper and more economical. Pig iron is the first step to making bar iron which is then used to make steel. The process that what used after the initial process is called the Bessemer process that allows steelmakers to create steel in huge quantities cheaper making it far more economical to create steel.
Improving the Steel Process
The Gilchrest-Thomas method was an improvement on the Bessemer process. The process was improved because the convertor was then lined with a basic metal to help remove phosphorus from the iron ore. As iron smelting and steel making methods evolved it became possible for steelmakers to use these methods to make steel for far less than before. This means that as steel making methods became simpler, the price of steel went down making it more affordable and easier to use in large scale buildings.
The steel industry began to grow with Carnegie Steel and the invention of the modern vehicle. Andrew Carnegie became the steel baron of the United States and was one of the forerunners in making steel a popular building material for just about every building type you could imagine. In 1980 alone there were more than 500,000 steel workers in the United States. Shortly after that in 2000 however the number fell to 224,000. The boom in China has made a great deal of increase in the demand for steel raising overall demand by 6%.
Though demand for steel has since dropped and the steel industry is currently suffering, there is hope for the future as steel has begun to again grow and become more popular. Steel is a material that works wonders and that helped build a nation and really bring a country out of the age of building with wood. Steel is a material that has helped shape the modern world as we know it today and that continues to shape and change the way we perceive our surroundings.
Today, one of the most common uses for steel, aside from skyscrapers of course, is corrugated steel buildings. Steel is a material that is going to stand the test of time and that is going to keep its shape, keep its integrity, and truly look great no matter what project you have in mind. Steel is a material that is going to work for a wide range of projects and that is going to be strong and durable. Steel has evolved to become a highly durable, usable, and affordable metal for all your projects making it the first choice for many projects and for many builders and companies.
If you want to learn more about steel buildings you can contact a professional company that can help you to find the building that is going to work for you and that is going to serve your needs. Steel is a truly amazing material, why not make it part of your home and part of your next building project or design plan.
