1) A content in excess of the maximum value stated is permitted if a phosphorus conten less than the maximum specified by 0.005% P per 0.001% N is observed. However, the nitrogen content shall not exceed a value of 0.012% in the cast analysis and 0.014% in the product analysis.
2) The specified maximum values do not apply if the steels are supplied with the RR(instead of R) type of deoxidization.
3) The content shall not exceed 0.55% Si and 1.60% Mn in the cast analysis or 0.60% Si and 1.70% Mn in the product analysis.
