What is steel | POUYA LOULEH

Steel is an alloy of iron with a carbon content of between 0.002 and 2.1% by weight. The properties of steel can be controlled by changes in the percentage of carbon, alloying elements and heat treatment. The use of steel is widely used in the construction of various industries such as construction, infrastructure, tools, ships, trains, automobiles, machinery, equipment and military weapons due to its high tensile strength and relatively low cost.
Today, new methods such as alkaline oxygen (BOS) steelmaking are used to produce steel, which in addition to reducing prices, has also led to an increase in the purity of the steel produced. Steel is one of the largest man-made materials and annually produces more than 1.6 billion tons of steel worldwide.
The strength of steel increases sharply with the "amount of dissolved carbon", but on the other hand, this increase in strength reduces the weldability and increases the likelihood of brittle failure. The strength of ferritic (ferromagnetic) steels is inversely related to ductility. Combining strength and ductility with austenitic (paramagnetic) phase stabilization in modern multiphase steels can be improved.
