a
FN = rimming steels not permitted; FF = fully killed steel (see 6.2.2).
b
For long products the P and S content can be 0,005 % higher.
c
The steels shall contain at least one of the following elements: Al total 0,020 %, Nb: 0,015 - 0,060 %, V: 0,02 - 0,12 %, Ti: 0,02 - 0,10 %. If these elements are used in combination, at least one of them shall be present with the minimum content indicated.
d
It is permissible to exceed the specified values provided that for each increase of 0,001 % N the P max. content will be reduced by 0,005 %; the N content of the ladle analysis, however, shall not be more than 0,012 %.
e
The steels may show a Ni content of max. 0,65 %.
f
The steels may contain max. 0,30 % Mo and max. 0,15 % Zr.
g
The max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % or if sufficient other N binding elements are present. The N binding elements shall be mentioned in the inspection document.
