Note:
1. The steels may show a Ni content of max 0.65 %;
2. For long SMA 50 AW steel, the P and S content can be 0.005% higher;
3. The SMA 50 AW steel may contain max. 0.30 % Mo and max. 0.15 % Zr
4. 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 %
5.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.
