Elements not quoted in this table should not be intentionally added to the steel without the agreement of the purchaser,except those intended for finishing the heat.All reasonable precautions shall be taken in order to prevent the addition of such elements from scrap or other materials used in the production process,which can affect the hardenability, mechanical properties and applicability To improve the performance of cold heading,it is possible to add Al:0,020 %to 0,050 % a Maximum values unless otherwise indicated. b In the case of steels with hardenability requirements (see Tables B.6 and B.Z),minor deviations from the specified limits are permitted (with the exception of sulfur and phosphorus),provided that they do not exceed 0,01 %for carbon and the values indicated in Table 2 for the other elements. c A lower silicon content or a specific silicon range may be agreed at the time of ordering
