1) Cast analysis.
2) Steels with improved machinability either by higher S levels up to about 0.10 % S (including controlled sulphide morphology) or Pb additions may be available on request. In the first case, the upper limit of the Mn-content may be increased by 0.15 %.
3) Steels may be supplied with a lower Si content. In this case, alternative means of deoxidation shall be used.
4) 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.
