Ferrous metals, their properties, features, and what you should know

Metals are divided into non-ferrous and ferrous. Ferrous metalsEssentially, it's iron, containing varying amounts of carbon and different crystal lattices. Ferrous metals include steels and cast irons, which in turn have a fairly large number of main classes. In the production of various types of cast iron and steel, specifically ferrous metals, extracted from metal ores. In the metals economy ferrous metals are more than 90%, indicating their widespread use. The percentage of carbon determines which properties the material will acquire—cast iron or steel. To improve quality ferrous metal, Alloying additives (other metals and alloys, as well as chemical elements) are used to improve the properties of alloys and impart the desired characteristics depending on their application. Common alloying additives include:

• copper;
• silicon;
• chromium;
• nickel.

Classification of ferrous metals

In most cases, classification of ferrous metals built on the basis of dividing elements according to their chemical composition and properties. The content of alloying elements determines the iron and its alloy. In turn, a certain percentage of carbon in an alloy indicates whether it is cast iron or steel. Cast irons contain more than 1.71 TP3T of carbon, while steels contain between 0.2 and 1.71 TP3T of carbon. Classification of ferrous metals implies division into the following classes:

• ferrous metals;
• refractory;
• uranium;
• alkaline earth metals;
• rare earth.

Also classification of ferrous metals This distinction is made between alloyed and unalloyed steels, also known as carbon steels. Carbon steels are steels in which carbon is the primary component, with impurities having little effect on the metal's properties. Alloy steels contain one or more alloying elements, which have a significant impact on the steel's properties. Alloy steels are widely used to manufacture critical components that bear heavy loads, undergo varying temperatures, and are subject to strong friction. This type of steel is widely used in mechanical engineering, tractor manufacturing, heavy industry, and other fields.

Types of ferrous metals

Types of ferrous metals steel have a wide range of applications. However, all types of steel are different and have their own purpose and area of application. Also, various types of ferrous metals, in particular steel, acquire distinctive properties after heat treatment. Many alloys are easy to roll, press, and cast. Others are soft enough to be machined by hand. types of ferrous metals Like stainless steel, with the right alloying elements, they have very high corrosion resistance, great hardness, and strength. This type of steel is successfully used in the food industry, medicine, household items, turbine production, and elsewhere. Another type of ferrous metal Cast iron is an alloy of iron and carbon, with a higher carbon content than steel. Because cast iron has good casting properties, it is primarily used for cast parts. Cast iron is divided into the following types:

• Foundry iron;
• Pig iron;
• Antifriction cast iron;
• Malleable cast iron;
• Low-alloy cast iron;
• High-alloy cast iron;
• Nodular cast iron;
• Vermicular graphite cast iron for castings.

Cast iron is used for casting, thanks to the presence of flake graphite. Malleable iron has remarkable ductility and is easily forged, hence the name. types of ferrous metalFor example, spheroidal graphite cast iron, due to its spheroidal structure, is used in the manufacture of parts of very high quality.
