What is EN 10083-2:2006+A1:2013

EN 10083-2:2006+A1:2013 is a technical standard that specifies the requirements for heat-treatable steels for quenching and tempering. This European Standard applies to steel products in the form of hot-rolled bars, rods, plate, strip, and wide flats, used for the manufacture of engineering components.

Composition and properties

The standard sets out the chemical composition of the steel grades, which must meet specific requirements in terms of carbon content, silicon, manganese, phosphorus, sulfur, chromium, nickel, and other elements. It also defines the mechanical properties such as tensile strength, yield strength, and impact energy values. By specifying these properties, EN 10083-2 ensures that the steel meets the necessary performance criteria for its intended applications.

Heat treatment process

EN 10083-2 provides guidelines for the heat treatment process of the steel grades covered by the standard. The heat treatment involves two main steps: quenching and tempering. Quenching is a rapid cooling process to harden the steel, while tempering is a controlled heating process to achieve the desired balance of hardness and toughness. The standard specifies the temperature ranges and cooling media to be used during these processes, ensuring the steel attains the desired microstructure and properties.

Applications

The steels conforming to EN 10083-2 are widely used in various industries due to their excellent mechanical properties and versatility. They find applications in the manufacturing of gears, crankshafts, axles, connecting rods, bolts, and other components where high strength, wear resistance, and toughness are crucial. The standard ensures that these steels can withstand demanding operating conditions and provide reliable performance in critical engineering applications.
