| a See 7 . 2 . b FN  = rimming steels not permitted; FF = fully killed steel (see 6. 2 ) . c For sections with nominal thickness > 100 mm  the C content by agreement. See Option 26, Clause 13 . d For long products the P an d S content can  be 0,005%     higher. e For long products the max. S content can  be increased for improved mach inability by 0,015 %    by agreement if the steel is    treated   to     modify   the    sulphide   morphology  and  the  chemical  composition   shows    min.0,0020 %     Ca.  See Option 27,    Clause 13 . f The max.    value for nitrogen does not apply if the chemical composition shows a  minimum total Al content of 0,015 %    or alternatively min.   0,013 %      acid  soluble  Al  or   if  sufficient  other  N  binding elements  are    present.      In  this  case   the  N binding elements shall be mentioned g   in the inspection document. g If other elements are  added, they shall be mentioned on  the inspection document. h For nominal thickness > 150 mm:   C = 0,22%   max. i For nominal thickness > 30 mm:   C =0,24%   max. j Applicable for long products only. k The steel may show a  Nb content of max.0,06 % ,  a V content of max.0,15 %   and a Ti content of max.0,06 % l For elements Ni, Cr and Mo the maximum value ( % )  is limited to  Ni=0,47; Cr=0,34 and Mo=0,14 . |
