The mechanical composition and chemical composition are important factors to consider when comparing the similarities and distinctions between S235JR and DX51 structural steel. In terms of mechanical composition, both S235JR and DX51 structural steel have a minimum yield strength of 235 MPa. This means that they have similar strength properties and can withstand a certain level of applied force or load before deformation occurs. However, there are also some distinctions in their mechanical composition. S235JR structural steel has a minimum tensile strength of 360-510 MPa, while DX51 structural steel has a minimum tensile strength of 270-500 MPa. This indicates that S235JR has a higher tensile strength, which means it can […]
