EN 10025-5:2019 - Hot rolled products of structural steels - Part 5: Technical delivery conditions for structural steels with improved atmospheric corrosion resistance

European foreword

This document (EN 10025-5:2019) 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of an identical text or by endorsement, at the latest by February 2020 and conflicting national standards shall be withdrawn at the latest by February 2020.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 supersedes EN 10025-5:2004.

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 10025-1:2004:

a) all dated and undated references to EN 10025-1:2004 to EN 10025-6:2004 are unchanged to this version with following exception: In 9.2.2.1 the references are 8.3.1 and 8.3.2 instead of 8.4.1 and 8.4.2;
b) Clauses 5, 12 and 13 of EN 10025-1:2004 are no longer relevant.

The main changes with respect to the previous edition are listed below:

a) part 5 is now a stand-alone standard for technical delivery conditions including the preparation of samples and test pieces, the test methods, the marking, labelling and packaging and the drawings;
b) for applications under the CPR this document and part 1 are to be used together;
c) requirements for elements not defined were added to 7.2.1 and 7.2.2;
d) Option 33 were added, Options 9 and 21 were deleted;
e) key to Figure A.1 was updated;
f) steel grades S355J4, S420J0W, S420J2W, S420J4W, S460J0W, S460J2W and S460J4W were added to Tables 1 to 5;
g) Annex B concerning the corresponding EURONORMS deleted;
h) references were updated and document editorial revised.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Republic of North Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in EN 10079 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses:

IEC Electropedia: available at http://www.electropedia.org/
ISO Online browsing platform: available at http://www.iso.org/obp

3.1 normalized rolled +N

rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent to that obtained after normalizing so that the specified values of the mechanical properties are retained even after normalizing

Note 1 to entry: In international publications for both the normalizing rolling, as well as the thermomechanical rolling, the expression "controlled rolling" may be found. However in view of the different applicability of the products a distinction of the terms is necessary.

3.2 as‑rolled +AR

conventional hot rolling without any normalized rolling or thermomechanical rolling and/or heat treatment condition like normalizing or quenching

3.3 thermomechanical rolling +M

rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition with certain properties which cannot be achieved or repeated by heat treatment alone

Note 1 to entry: Thermomechanical rolling leading to the delivery condition +M can include processes with an increasing cooling rate with or without tempering including self‑tempering but excluding direct quenching and quenching and tempering.

Note 2 to entry: In some publications the word TMCP (Thermomechanical Control Process) is also used.

3.4 normalizing +N

heat treatment consisting of austenitizing followed by air cooling

3.5 steel with improved atmospheric corrosion resistance

steel in which a certain number of alloying elements, such as P, Cu, Cr, Ni, Mo, has been added in order to increase its resistance to atmospheric corrosion, by forming an auto‑protective oxide layer on the base metal under the influence of weather conditions

Note 1 to entry: Steel with improved atmospheric corrosion resistance is often called weathering steel.

Note 2 to entry: Additional information for the use of steel with improved atmospheric corrosion resistance is given in Annex B.

The N binding elements shall be mentioned in the inspection document. ^g Cr may be reduced to 0,32 % if the chemical composition shows a minimum Si content of 0,15 %.

7.3 Mechanical properties

7.3.1 General

7.3.1.1 Under the inspection and testing conditions as specified in Clauses 8, 9 and 10 and in the delivery condition as specified in 6.3 the mechanical properties shall comply with the values given in Tables 4 and 5.

Stress relieving at more than 580 °C or for over 1 h can lead to a deterioration of the mechanical properties of the steel grade. For normalized and normalized rolled flat products the maximum stress relief temperature should be 560 °C. If the purchaser intends to stress relief the products at higher temperatures or for longer times than mentioned above the minimum values of the mechanical properties after such a treatment should be agreed upon at the time of the order.

7.3.1.2 For flat and bar products ordered and supplied in the normalized or normalized rolled condition (delivery condition +N) the mechanical properties shall comply with the relevant tables for mechanical properties in the normalized or normalized rolled condition or after normalizing by heat treatment after delivery or after hot forming if the provisions of CEN/TR 10347 are satisfied.

Products can be susceptible to a deterioration in mechanical strength if they are subjected to incorrect heat treatment processes at higher temperature such as flame straightening, rerolling, etc. Products in the +N delivery condition are less sensitive than other delivery conditions, but it is recommended that guidance is sought from the manufacturer if any higher temperature processing is required.

7.3.1.3 For flat products the nominal thickness applies. For long products of irregular section the nominal thickness of that part from which the samples are taken applies (see Annex A).

Annex B (informative) Additional information for the use of steel with improved atmospheric corrosion resistance

The corrosion inhibiting effect of the auto‑protective oxide layer relates to the nature of its constituents and to the particular distribution and concentration of alloying elements in it. The resistance to atmospheric corrosion depends on weather condition having a succession of dry and wet periods for the forming of the auto‑protective oxide layer of the base metal. The protection afforded depends on the environmental and other conditions prevailing at the site of the structure.

Provisions should be made in the design and the fabrication of the structure for the auto‑protective oxide layer on the surface to form and regenerate itself unimpeded. It is the responsibility of the designer to include corrosion of unprotected steels in his calculation and, as far as is necessary, to compensate for this by increasing the thickness of the product.

A conventional surface protection is recommended when the content of particular chemical substances in the air is significant and absolutely necessary where the structure is in contact with water for long periods, is permanently exposed to moisture, or is to be used in a marine atmosphere. Before painting, the products should be descaled. Under comparable conditions, the susceptibility to corrosion of steel with improved atmospheric corrosion resistance under painting is less than that for conventional structural steels.

The surfaces of structures which are not exposed to the elements but may be subject to the build‑up of condensation, should be appropriately ventilated. Otherwise, a suitable surface protection is necessary. The extent to which these factors depend on the prevailing climatic conditions in the widest sense and on the details of the structure do not permit any generally valid statements on the corrosion process. The user should therefore consult the manufacturer of the steel regarding the suitability of the products for each individual application.

Annex C (informative) Notes on fabrication

C.1 Weldability

If filler metal without improved atmospheric corrosion resistance is used ensure that the weld itself is weather resistant.

Before welding, any surface layer which has already been formed should be removed to a distance of 10 mm to 20 mm from the joint edges.

Special precautions should be taken when welding steel grades S355J0WP and S355J2WP with a high phosphorus content.

General requirements for arc welding of the steels specified in this document are given in EN 1011‑2.

NOTE With increasing product thickness and strength level cold cracking can occur. Cold cracking is caused by the following factors in combination:

the amount of diffusible hydrogen in the weld metal;
the presence of hardening structures (martensite and/or bainite) in the heat affected zone;
significant tensile stress concentrations in the welded joint.

C.2 Riveting and bolting

In case of assembling by riveting and bolting, precautions should be taken with regard to the choice of rivets and bolts to be used for assemblies in order to prevent the start of the corrosion process.
