Key features of the system
The minimum specified characteristic yield strength is 500 N/mm2 for bar diameters 16 - 50 mm and 555 N/mm2 for the 63.5 mm diameter bar. 16 - 50 mm bars can be welded using appropriate industry practices relative to the carbon content of the steel. Welding of the higher grade 63.5 mm diameter bar is not recommended
