Tighter carbon ranges may be agreed at the time of enquery and order
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.
Elements not listed in this table shall not be intentionally added to the steel without the agreement of the purchaser except for finishing the cast.
