a See 7.2. b FN = rimming steels not permitted; FF = fully killed steel (see 6.2.2). c For sections with nominal thickness > 100 mm the C content by agreement. See option 26. d For long products the P and S content can be 0,005 % higher. e For long products the max. S content can be increased for improved machinability 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. f The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % or alternatively min. 0,015 % acid soluble Al or if sufficient other N binding elements are present. In this case the N binding elements shall be mentioned in the inspection document. g Cu content above 0,40 % may cause hot shortness during hot forming. h If other elements are added, they shall be mentioned on the inspection document. i For nominal thickness > 150 mm: C = 0,20 % max.. j For grades suitable for cold roll forming (see 7.4.2.2.3): C = 0,22 % max.. k For nominal thickness > 30 mm: C = 0,22 % max.. l Applicable for long products only. m The steel may show a Nb content of max. 0,05 %, a V content of max. 0,13 % and a Ti content of max. 0,05 %. |
