Factories and pollution go hand in hand. As steel industries sprang across the world, the level of pollution in the air began to rise. With no research and debate about health issues due to air pollution, it was important to devise new methods to manufacture steel and to keep the pollution in check.
In 1912, Harry Brearly, a British metallurgist, while experimenting with chromium, found that a layer of that metal on steel made steel resistant to weathering and acid. It was the perfect solution for preserving the life of gun barrels.
There were vast untapped resources of iron in the West. The United States produced only one-fifth of the total iron that England had produced. Post the Civil War, however, American industrialists focused on the Bessemer process and gave birth to a steel industry that would reap more profits than the Gold Rush of 1849. American steel would be used to build roads, bridges, and railway tracks across the country.
Gone were the days of the ancient iron and steel weapons. Fast forward to the age of powerful and beautifully-crafted swords. Swords were being made around the world.
Steel, as we know it, is widely used to build skyscrapers, bridges, and other infrastructure. But there is a long history associated with the production of steel, and the numerous iterations and trial-and-errors it took to perfect the product. Modern steel contains 98-99% of iron, with rest being composed of carbon, which gives steel its tensile strength.
Steel is known to be a vital ingredient used in construction, in fact, the most robust when it comes to holding a structure. The durability and sturdiness that steel provides to a building are unmatched by concrete, wood, or bamboo.
A crucial aspect of managing any construction project—be it small scale or large scale—involves the planning and control of the cost. Cost control procedures are typically employed to make sure that a project costs no more than intended.
The last few years have seen the Indian steel sector facing many problems. Despite the hardships, India was the third largest producer of steel in the world for the year 2017. Domestic availability of iron ore and cost-effective labor has propelled the Indian steel sector towards growth.
Since its independence, India has seen an unprecedented growth in infrastructure and energy usage. It has made its mark not just in Asia, but all over the world, because of its rapid rate of urbanization and modernization.
