◎ The carbon steel series of the French NF EN standard is equivalent to the engineering non-alloy steel of the European standard (EN), and its mechanical properties are the same as the similar non-alloy steel in Germany.
◎ NF old steel number from [NF A35-501 (1983)].
◎ If additional elements are added, they should be mentioned in the inspection report.

※ For sections with nominal thickness > 100 mm the C content by agreement.
① For long products the P and S content can be 0,005 % higher.
② 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.
③ Cu content above 0,40 % may cause hot shortness during hot forming.
④ 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.
