① For the steel grades E235, a controlled sulfur content ranging from 0.015% to 0.040% is specified to improve the machinability. It is to be adjusted by resulfurization of the steel after maximum desulfurization or alternatively by secondary metallurgical processes with a reduction of the oxygen content.
