A typical composition of steel consists of: Fe/C - 3.5, Methylene-Chloride (MCC) - 0.5, Chromium (III) - 0.7 and Oxide (OH) - 0.2.

These elements can be combined in countless ways, resulting in all sorts of compositions of steel. The composition of steel affects its wear and tear characteristics, stress corrosion resistance, ability to withstand, etc.<br><br><br>The composition of steel can be categorised into three distinct categories - iron (Fe) - carbon steel (CC) - and chromium (III) - steels. The composition of steel varies with the type of material it is made up of, i.e. pure iron (I) is much stronger than alloyed iron (A), which is usually lighter and more malleable. Thus, the composition of steel generally depends on the alloyed version of the material.<br><br><br>The chemical composition of steel depends on the method of its production. For example, stainless steel, which is often coated with chromium, undergoes an oxidation reaction with carbon under high heat and pressure. This carbon reaction produces carbon steels, which are known for their excellent combination of hardness, flexibility, and ductility. The material's ability to resist corrosion also depends on the method of its manufacturing, which includes carbon etching, welding, and baking. Thus, the composition of steel often varies with the process of production.<br><br><br>Iron is the most abundant element in the earth's crust. A variety of alloys based on iron are used to create steel. The best-known types of steels are hardened steel (or cold rolled) and cast iron. Cast iron is a kind of metal that undergoes a complex transformation during the making process. During this transformation, one can notice two major properties: hardness and ductility.<br><br><br>Hardness refers to the material's ability to resist indentation and stress. The most important physical characteristic of steel (which affects both its price and strength) is its hardness, which is defined as a property that is neither a minimum nor a maximum; rather, it lies somewhere in between them. Thus, when purchasing steels, you need to check if they are categorized under 'hardness' or not. It is always better to go for the steels with the highest percentage of pure iron because this increases the resistance of the alloying element.<br><br><br>Ductility refers to the capability of the steel to form ducts. The greater the ductility, the better is the ability of the steel to absorb shock and reduce the stress that is placed on it during usage. Thus, the higher the ductility, the more rigid is the steel (and the weaker). For this reason, when purchasing a good grade of steel, you should prefer the steels with higher percentages of ductility.<br>' |
