20CrMo4 is a low-alloy steel grade with good hardenability and machinability. This steel is supplied in hot rolled and cold drawn conditions, suitable for applications where a combination of high strength with wear resistance or fatigue resistance is required. It is used for heavy duty components that are subject to the highest stresses, such as for the drive shafts of tractor-trailers and heavy trucks, cranes and other construction equipment.
20CrMo4 is a low-alloy chromium-molybdenum steel that offers mechanical properties with good corrosion resistance, wear and tear resistance and fatigue resistance. Its low carbon content ensures good weldability and formability. It has a balanced chemical composition and can be supplied in the normalised, pre-hardened and tempered conditions, making it suitable for a wide range of uses.
The primary application of 20CrMo4 is in the automotive industry, where it is used extensively in the production of light to medium duty vehicles such as trucks, buses, cars and utility vehicles. It is also used in the construction industry, particularly in the manufacture of high-strength components such as crane arms and ladders, as well as in the manufacture of industrial machinery, such as tube and pipe rollers, conveyor rollers and power tools.
It is also commonly used in the manufacture of structural parts such as seat frames and supports, automotive springs, and for the assembly of engines and power plant components. In the aerospace industry, 20CrMo4 steel is used to produce aircraft components and fasteners due to its strength and toughness.
20CrMo4 steel can be supplied in a range of forms, including hot rolled and cold drawn bars, plates, strips and sheets. It also comes in forgings, castings and welded components. In addition, it can be delivered in the normalized or hardened & tempered condition. It offers good wear resistance, fracture toughness and fatigue strength, making it ideal for use in the manufacture of components that must resist wear, stress and fatigue.
Because it is a low-alloy grade of steel, 20CrMo4 is generally produced by normalizing the material, which involves a heating and cooling cycle to provide consistent mechanical properties across the entire material. After normalizing, it can be supplied in the pre-hardened or tempered condition if required.
20CrMo4 steel is popular in the manufacture of components that require high levels of strength, such as those found in construction and industrial equipment and aircrafts. Its good wear and fatigue resistance makes it suitable for a variety of applications, from power tools and industrial machinery to automotive components and aerospace components. As this steel has good weldability and forming properties, it is also suitable for use in the manufacture of welding and forming components.
Overall, 20CrMo4 is a great choice of steel for applications that need a combination of strength, toughness and wear resistance. Its good weldability, formability and hardenability make it suitable for a wide range of uses and makes it a popular choice for engineers and designers looking for a low-alloy steel grade with good properties.
