What is ASTM equivalent of st52-3 steel coil/sheet and their difference

The capital letter H in S355J0H and S355J2H stands for ""Hollow section"", which respectively represents the pipe of S355J0 and S355J2.The Executive Standards of S355J0 steel and S355J2 steel, st52-3 steel coil/sheet are both EN 10025-2, the difference is that they have different temperature requirements for impact energy: S355J0 - impact energy at 0 ℃ is required to be ≥ 27J. S355J2: impact energy at - 20 ℃ is required to be ≥ 27J.

What are the characteristics of medium and thick plate, st52-3 steel coil/sheet? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, st52-3 steel coil/sheet is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

In recent years, in line with the development trend of iron and st52-3 steel coil/sheet steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which st52-3 steel coil/sheet are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

The Secretary General of the association of large st52-3 steel coil/sheet steel producers in Pakistan said that steel is the pillar of Pakistan's construction industry, and Pakistan's economy cannot bear the consequences of the long-term closure of the steel industry. Any delay in the resumption of production will lead to the failure of the government's plan to revitalize the construction industry, which will have a negative impact on Pakistan's economy. It is hoped that the government will immediately resume st52-3 steel coil/sheet production in the steel industry, especially those that are able to provide shelter for workers.
