1) Cast analysis.
2) The steel shall be supplied in the fully killed condition.
3) Steels may be supplied with a lower silicon content. In this case, alternative means of deoxidation shall be used.
4) Steels with improved machinability either by higher S levels up to about 0.10 % S (including controlled sulfide morphology) or Pb additions may be supplied on request. In the first case, the upper limit for the Mn content may be increased by 0.15 %.
5) Cu content above 0.40 % can cause hot shortness during hot forming.
6) Fe is listed as a Base element for this material, but its % value is not listed in the specification. The value shown is a calculated one.
