')The steels shall contain at least one of the following elements: A1 total 20.020%. Nb. 0.015 to 0.06096, V 0.02 to 0.1296, "k 0.02 to 0.10%. If these elements are
used in combination, at least one of them shall be present with the minimum of content indicated.
2)It is permissible to exceed the specified values provided that 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 show a Ni content of max. 0.65%.
4)The steels may contain ma. 0.30% Mo and max. 0.15% Zr.
%'he max. value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0.020% or if sacient other N binding elements are
present. The N binding elements shall be mentioned in the inspection document
