EN 10083-3 steel plate

EN10083-3 steel plate introduction: EN 10083-3 2006 steel plate is a kind of alloy steel for quenching and tempering. Technical delivery conditions for alloy steels. There are steel grades 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, 27MnCrB5-2. EN 10083-3 steel plate has high strength, high toughness and good hardenability. This alloy needs the high temperature preheating before welding in order to eliminate the stress after welding processing.
