Fe510C2KI Steel

Method of deoxidation FN = rimming steels not permitted
For long products the P and S content can be 0.005% higher
The steels may show a Ni content of max. 0,65 %
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 %
The steels may contain max. 0,30 % Mo and max. 0,15 % Zr
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
