◎ 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.
