Prone to rust: since it is mainly composed of iron, the material is prone to rust and will eventually be damaged if it rusts continuously. Frequent contact with moisture will only accelerate the process, but damage is inevitable. So, do you want to know the differences between cast iron and steel? Is steel stronger than iron? Read on as we provide answers to these questions and to the advantages and disadvantages of these two metals. Choosing between these metals will require knowing the pros and cons of both metals.
The following are their advantages and disadvantages. So between cast iron and steel, which one do you prefer? Having seen the advantages and disadvantages of both types of materials, which one you choose to use will ultimately depend on the requirements of the product. Look around the factory and, as sure as day, a glittering array of metal instruments and machinery will stare at you. If it weren't for some incredibly versatile metals, many of these tools and the products and services that the process industry specializes in simply couldn't be produced on a massive industrial scale.
The PIF examines the advantages and disadvantages of several metals that are commonly used in manufacturing. Have you noticed how some materials rust over time due to prolonged exposure to the environment? These materials invariably contain iron and are called ferrous metals. Ferrous metals are those that contain considerable amounts of iron. The Latin name for iron is Ferrum and therefore metals containing iron are “ferrous”).
Pure iron is very soft, has a greyish-white appearance and has limited uses. Iron is rarely found in its pure form (except in meteorites). It exists in nature together with other elements, such as minerals. The most common mineral is iron oxide.
Minerals with a significant iron content are called iron ores; the commonly found iron ores are hematite and magnetite. Iron is obtained from iron ore by smelting, in a blast furnace. The iron thus obtained is called pig iron, which constitutes 92-94% of iron and 3-5% of carbon, together with small amounts of other elements. Cast iron is brittle and has limited uses.
Therefore, it is used to manufacture different types of ferrous metals. Cast iron is generally poured into furnaces (electric arc, induction, open fireplace or blast furnaces) and combined with other elements to form various ferrous metals. The molten material is directly molded into the required shape or rolled (hot, hot or cold, depending on the application). In addition, it undergoes heat treatment (annealing, tempering, cooling, etc.) Ferrous metals have improved physical properties, such as great durability, ductility and high tensile strength, and find a wide variety of commercial and industrial applications.
The most common ferrous metals are hardened steel, carbon steel, alloy steel, stainless steel, wrought iron and cast iron. Hardened steel, which is relatively softer, is used to make steel plates, while carbon steel, being harder, is used in shafts and pulleys. In addition, carbon steel is used to cut other metals and is used in machine tools, knives and drills. In addition to the various applications listed above, ferrous metals have several advantages over non-ferrous metals.
Aluminum), which do not contain iron, ferrous metals are prone to rust when exposed to even small amounts of moisture. However, some stainless steel grades are an exception, due to the presence of chrome. Ferrous metals can be easily combined with other elements to improve their resistance to corrosion. This property, together with great durability, high strength and ductility, make ferrous metals very versatile and suitable for a wide variety of applications in various industries.
