European standard S460G2+QT offshore engineering steel plate

S460G2+QT plate is a type of European standard steel plate, which belongs to weldable structural steel for fixed coastal structures. Its delivery state is quenched and tempered, and the impact is -40 degrees impact test. The 2 after G represents the related numbers of this steel characteristic, as for the latter +QT means quenching and tempering, it is just a method of naming steel grades in the standard.

S460G2+QT steel plate executive standard: implement EN10225-2009 standard.

S460G2+QT offshore engineering steel plate manufacturing process:
a. Steel is produced by alkaline oxygen or alkaline electric arc furnace process. All steel grades must be fully killed and fine-grained steel. In addition, the third type of steel must be vacuum degassed or ladle refining treatment.

b. Thickness limitation and segregation control
1) For the second and third types of continuous casting steel ingots, if the relevant product meets all the relevant requirements of this European Standard, the manufacturer shall deal with the maximum thickness of the continuous casting ingot as appropriate.
2) Except for the pile reduction ratio of 3:1, the rolling reduction ratio of the continuous casting materials used to manufacture steel plates should be 4:1
3) The intermediate or final product produced by the continuous casting process should be checked for segregation of the central component according to the manufacturer's method or the ordering party's agreement.

S460G2+QT offshore engineering steel plate application range:
S460G2+QT belongs to a series of high-strength structural steel products with good comprehensive mechanical properties, welding properties and process properties. It is suitable for manufacturing structural parts such as offshore and offshore oil production platforms and terminal equipment.
