• FN= rimming steels not permitted; FF = fully killed steel

① For sections with nominal thickness > 100 mm the C content by agreement
② For long products the P and S content can be 0,005 % higher.
③ 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. 0,002 0 % Ca
