Comparing the two standards, the latter eliminates the controlled rolling delivery condition. In the former standard, the upper yield strength is specified; in the latter, it has been replaced by the lower yield strength. Additionally, for thicknesses greater than 16 mm, the yield strength has been increased by 10 MPa. There are also several other changes; please refer to the respective standards for details.
