The leading EN steel grade S355J2 plates supplier and exporter in China

Continuous rolled steel plates and single rolled steel plates EN steel grade S355J2 plates are often used in many industries. Although the appearance of these two steel plates is very similar and they are same steel grades, in some respects, they belong to two different plates. Because the continuous rolled steel plate is made of strip steel by uncoiling, leveling and shearing, its EN steel grade S355J2 plates comprehensive mechanical properties are not as good as the single rolled steel plate, so some important occasions would choose single rolled steel plate but not continuous rolled steel plate.

A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. EN steel grade S355J2 plates, A588 Grade Acould be produced in 200mm in our company.

The effect of alloy elements on the properties of heat treatment methods for thick steel plate: the performance of heat treatment method reflects the difficulty coefficient level of heat treatment process and the tendency of defects caused by heat treatment process. The key points include cutting performance, over temperature sensitivity, quenching aging tendency and air oxidation carburizing tendency. EN steel grade S355J2 plates, Carbon steel has high machinability, and slow cooling method can be used in heat treatment, which can reduce the deformation and cracking tendency of the products. The addition of Mn and Si will increase the over temperature sensitivity of steel.
