European foreword
This document (EN 10025-4:2019) has been prepared by Technical Committee
CEN/TC 459/SC 3 “Structural steels other than reinforcements”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical
text or by endorsement, at the latest by February 2020 and conflicting national standards shall be
withdrawn at the latest by February 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document will supersede EN 10025-4:2004
This document consists of the following parts, under the general title Hot rolled products of structural steels:
— Part 1: General technical delivery conditions
— Part 2: Technical delivery conditions for non-alloy structural steels
— Part 3: Technical delivery conditions for normalized/normalized rolled weldable fine grain structural
steels
— Part 4: Technical delivery conditions for thermomechanical rolled weldable fine grain structural steels
— Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion resistance
— Part 6: Technical delivery conditions for flat products of high yield strength structural steels in the
quenched and tempered condition
For a short transition period there will be a coexistence of EN 10025-1:2004 with EN 10025-2:2019 to
EN 10025-6:2019, since the new EN 10025-1 has to fulfil the requirements of the CPR and will therefore be
published later. For this short transition period up-to-the publication of the next edition of part 1 the
following is to be taken into account for EN 10025-1:
