Chemical composition % of the Product analysis of grade S355J2WP （1.8946）
For long products the P and S content can be 0,005 % higher.
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.
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 show a Ni content of max. 0,65 %.
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. The N binding elements shall be mentioned in the inspection document
