① For long products the P and S content can be 0.005% higher.
② For railway applications a maximum S content of 0.010% may be agreed at the time of enquiry and order.
③ If sufficient other N-binding elements are present the minimum total Al content does not apply.
④ Cu content above 0.40% may cause hot shortness during hot forming.
