① For long products the P and S content can be 0.005% higher.
② For some applications, e.g. for railways, a maximum S content of 0,010 % may be agreed upon at the time of the order.
③ If sufficient other N-binding elements are present the minimum total Al content does not apply.
④ For long products of the grades S420 a maximum C content of 0,18 % applies. 碳當(dāng)量計(jì)算
