For long S235J2W steel plate 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: 0,010 - 0,065 %, V: 0,01 - 0,14 %, Ti: 0,01 - 0,12 %. 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 S235J2W steel plate analysis, however, shall not be more than 0,013 %.
The S235J2W steel plate may show a Ni content of max. 0,70 %. 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.
Steel grade: S235J2W Standard: EN 10025-5 :2004 European standard for hot-rolled structural steel. Structural steels with improved atmospheric corrosion resistance - technical delivery conditions.
