1) Cast analysis.
2) The steel shall be supplied in the killed condition.
3) Steel may be supplied with a lower Si content. In this case, alternative means of deoxidation shall be used.
4) In the case of grades with specified 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 C ±0.01 %, and in all other cases, the values according to ISO 683-1 – Table 4.
5) 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 for the Mn content may be increased by 0.15 %.
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.
