1) Cast analysis.
2) The steel shall be supplied in the killed condition.
3) Where requirements are made on hardenability, slight deviations from the limits for the cast analysis are permitted, except for P and S; these deviations shall, however, not exceed in the case of carbon ±0.01 % and in all other cases the values according to BS EN 10084 – Table 4.
4) Steels with improved machinability as a result of the addition of higher S contents up to around 0.10 % S (including resulfurized steels with controlled inclusion content (e.g. Ca-treatment)) or Pb 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.
