What is EN 10025 material

What is EN 10025 material?

 

EN10025 is a European standard mainly used for the production of low alloy structural steel high strength steel plates, such as S355J2+N. This standard covers a variety of grades, including but not limited to S235JR, S235JR+N, S235JR+M, S235J0, S235J0+N, S235J0+M, S235J2, S235J2+N, S235J2+M, S275JR, S275JR+N, S275JR+M, S275J0, S275J0+N, S275J0+M, S275J2+N, S275J2 ... 5J2, S275J2+N, S275J2+M, S355JR, S355JR+N, S355JR+M, S355J0, S355J0+N, S355J0+M, S355J2, S355J2+N, S355J2+M, S355K2, S355K2+N, S355K2+M, S450J0, S450J0+N, S450J0+M. These steels are mainly used in the manufacture of pressure vessels, ultra-low temperature equipment, marine engineering, hydropower engineering, nuclear power engineering, engineering machinery and other fields.
