Chemical Composition (%) - EN 10088-2-2005
Particular ranges of sulphur content may provide improvement of particular properties. For machinability a controlled sulphur content of 0.015% to 0.030% is recommended and permitted. For weldability, a controlled sulphur content of 0.008% to 0.030% is recommended and permitted. For polishability, a controlled sulphur content of 0.015% max is recommended.
