EN8 Medium Carbon Steel: Properties, Applications, and Supply Cases by TJC Steel

​Introduction
EN8, also known as 080M40 in Europe, is a medium carbon steel that offers a balance of strength and ductility. It is widely used in various industrial applications due to its excellent mechanical properties and relatively low cost. In this article, we will explore the chemical composition, mechanical properties, heat treatment states, dimensional ranges, and primary applications of EN8 medium carbon steel. We will also delve into specific supply cases handled by TJC Steel.
Chemical Composition
The chemical composition of EN8 steel is tailored to provide the desired mechanical properties. It typically contains 0.75-0.85% carbon, along with manganese, silicon, sulfur, and phosphorus in controlled amounts. The carbon content is higher than that of low carbon steels, but lower than high carbon steels, giving EN8 its unique combination of strength and ductility.
Mechanical Properties
The mechanical properties of EN8 steel are excellent, making it suitable for a wide range of applications. It exhibits high yield strength and tensile strength, coupled with good impact resistance and fatigue strength. The ductility of EN8 allows it to be formed and machined easily, while maintaining good toughness even at low temperatures.
Heat Treatment States
EN8 steel can be heat-treated to achieve different mechanical properties and microstructures. Common heat treatment methods include annealing, normalizing, and quenching and tempering. Annealing is used to soften the steel and improve its machinability, while normalizing removes internal stresses and improves dimensional stability. Quenching and tempering are used to increase the hardness and strength of the steel, making it suitable for more demanding applications.
Size Range
TJC Steel offers EN8 medium carbon steel in a wide range of sizes and dimensions. This includes round bars, flat bars, and plates, with thicknesses ranging from a few millimeters to hundreds of millimeters. Customers can choose from standard sizes or request custom dimensions to meet their specific requirements.
Primary Applications
EN8 medium carbon steel finds applications in numerous industries due to its balance of strength and ductility. It is commonly used in the automotive industry for components like gears, axles, and shafts that require durability and precision. It is also used in the construction industry for structural members and fasteners. Additionally, EN8 steel is suitable for general engineering applications, machine tooling, and forging operations.
