EN 10083-3:2006 Steel Plate is an alloy steel material designed for quenching and tempering applications. This European standard specifies the technical delivery conditions for alloy steels used in engineering and structural applications requiring high mechanical performance. Common steel grades covered under this standard include 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, and 27MnCrB5-2.
EN 10083-3:2006 steel plates are characterized by high strength, excellent toughness, and good hardenability, making them suitable for components subjected to heavy loads, impact, and wear. These steels can achieve enhanced mechanical properties after appropriate heat treatment processes such as quenching and tempering.
Due to the alloy composition and high hardenability of these materials, high-temperature preheating is generally required before welding in order to reduce the risk of cracking and eliminate welding stress after fabrication. Because of their excellent mechanical performance, EN 10083-3:2006 steel plates are widely used in machinery manufacturing, automotive components, heavy equipment, gears, shafts, and structural engineering applications.
