1) Cast analysis.
2) The steel shall be supplied in the killed condition.
3) For steels with hardenability requirements, except for P and S, insignificant deviations from the limits for cast analysis are permissible; these deviations shall, however, not exceed in the case of carbon ±0.01 % and in all other cases the values according to ISO 683-3 – Table 4.
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) 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.
