Steel is an alloy of Iron & Carbon. The percentage of Carbon in the alloy should not exceed 2%. Other metals are sometimes added. There are three methods of Steel production: the open-hearth method, the converter method & the electric arc method. The open-hearth method involves melting Steel in open-hearth furnaces. This method produces high-quality Steel in large quantities at a low cost. However, it is a lengthy & labor-intensive process. The converter method is resulting also of high quality Steel & the time required for its production has been significantly reduced. The third method commonly used for manufacturing cutting tools involves the production of Steel in high-frequency electric furnaces. This method produces the highest quality Steel, which is pure & free from impurities such as gases & sulfur. Steel is associated with the planet Mars. Since this metal is an alloy of Carbon & Iron, it also has the protective properties of Iron. This means ...
