Steel is a versatile metal that can be employed for a variety applications. Steel is used in more than 55% of all cars. The type of alloys that are used to create it determines its versatility, as they affect the quality, durability, and strength. For instance, the method the process of cooling the metal can have a significant effect on the microstructure of the metal and its overall properties. It can be manipulated in order to achieve specific properties such as machinability, yielding strength, and resistance to corrosion.
In its simplest form, steel is iron that has been alloyed with various elements to enhance its physical properties and make it suitable for certain uses. The proportion of the additional alloying elements determines the category of steel a steel is part of and its overall performance in different applications.
For instance stainless steel has at least 11% chromium. This makes it resistant to corrosion. This is what makes it suitable for a range of applications like kitchen utensils and cutlery. Tool steel is popular because of its hardness and resistance to abrasion. It is also used to hand tools and machine dies. Additionally, the high weldability and ductility of carbon steels makes them ideal for a broad array of applications. Electrical steel is a special steel grade that contains silicon (typically around 3%) This enhances the magnetic properties, and also reduces eddy-current losses. It is therefore ideal for laminations and transformer cores of electric motors.
