4135/4140/4142/6150 Alloy Plate EN10083-3
EN 10083-3:2006 steel is an alloy steel designed for quenching and tempering processes. This standard governs the technical delivery conditions of alloy steels, including grades such as 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, and 27MnCrB5-2. EN 10083-3 steel plates exhibit high strength, exceptional toughness, and good hardenability. The alloy necessitates high-temperature preheating before welding to alleviate stress post-welding.
