Chemical composition %   of   steel   (1.8903):   EN 10025-3-2004
Nominal thickness =< 63(mm) CEV max = 0.53
Nominal thickness from 63 to 100 (mm) CEV max = 0.54
For long products the P and S content can be 0.005% higher
For railway application a maximum S content of 0.01% may be agreed at the time of enquiry and order
In sufficient other N-binding elements are present the minimum total Al content does not applay
Cu content above 0.4% may cause hot shortness during hot forming
