S355JR steel is widely used in the structural engineering and constructions. The application is mainly decided by S355JR mechanical properties and require S355JR steel have high strength. S355JR yield strength and S355JR tensile strength have close relationship to the thickness of S355JR steel plate.
S355JR mechanical properties:
| Grade | Number | ReH Minimum Yield strength (MPa ) for nominal thickness(mm) |
R m (MPa) for nominal thickness (mm) |

From S355JR mechanical properties, we can find that S355JR yield strength and S355JR tensile strength reduced with the increasing of S355JR steel plate thickness. BBN steel can provide full thickness ranges of S355JR steel plates with reasonable price and quality. BBN S355JR steel plates have been exported to more than 70 countries in the world.
