GB/T11251 1345 Alloy Structural Steel Coil

GB/T 11251 alloy steel is one of the common hot-rolled alloy structural steel coils. GB/T 11251 Hot-rolled coil has high strength and wear resistance, high hardenability, moderate cold deformation plasticity, good cutting performance and good welding performance. During the heat treatment, the toughness of the steel decreases less. GB/T 11251 alloy steel can still maintain high toughness under water cooling conditions, but it has a tendency of overheating sensitivity, white spot sensitivity and temper brittleness.

EN 10083-3 4135/4140/4142/6150 Alloy Structural Steel Coil

EN 10083-3:2006 steel is an alloy steel used for quenching and tempering. This standard regulates the technical delivery conditions of alloy steels. Under the steel 50CrMo4, 51CrV4, 20MnB5, 34CrMo4, 42CrMo4, 27MnCrB5-2. EN 10083-3 steel plate has high strength, high toughness and good hardenability. The alloy requires high temperature preheating before welding to eliminate the stress after welding.
