National foreword This British Standard has been prepared under the direction of the Iron and Steel Standards Policy Comm ittee and is the E ng l ish language version of EN 10 025 'Hot rolled products of non-al loy structural steels : Technical del ivery condition' ratified by C E N/BT on 30 M a rch 1 990. It super· sedes parts of BS 4360 : 1 986 which is withdrawn. The parts of BS 4360: 1 986 not affected by EN 10 025 wi l l be publ ished simultaneously with this standard as a new edition of BS 4360. As further European Standards for structural steels become avai lable it is anticipated that the E ngl ish language versions will be published as fol lows: BS EN 1 0 1 1 3

Part 1

At 1the time of publication of this standard not all of the reforenced Euronorms ( E U) in clause 2 had been trans· formed i nto mandatory European Standards (EN). Until each of these Euronorms is transformed i nto a European Stan dard, EN 10 025 permits either implementation of the requi rements of the Euronorms or implementation of the requirements of the correspo nding British Standards (BS) (see footnote 1 to cl ause 2 and annex B). To ensure that users know what is to be supplied when products are ordered and supplied in accordance with this standard the responsible BSI Technical Committee has agrned that the standards to be applied ( E N, EU, ISO or BS) are given in table B.1 of national appendix B. It should be noted that as each Euronorm is transformed into a European Standard the requirements of the Euro pean Standard become mandatory. Appropriate amend ments to/revis ions of/new editions of this standard will be issued as necessary. When adopting the text of the European Standard, the following textual error was discovered. It has been marked in the text and has been reported to ECISS/TC 10 in a proposal to amend the text of the Eur1 o pean Standard.

Textual error.

In table 10, against the designations Fe 5 1 0 DD1 and Fe !5 10 DD2, the UK equivalent should be 50 DD i n both cases. Compliance with a British Standard does not of itself con1fer immunity from legal obligations.

Techn ical delivery conditions general requi rements

As explai ned i n 6.2, the designation system used in this standard is based on Euronorm 27-74 'Designations of steels'. The responsi bi le BSI Techn ical Committee has agreed that these designations should be used when referenci ng steel grades in accordance with this standard. For the UK ed ition of this standard only grades Fe 360 A, Fe 430 A and Fe 510 A are specified i n annex D 'Non· confl icting national add itions'. These are the former grades 40A, 43A and 50A in BS 4360:-1 986 which have been redesignated for consistency with the designations of the other grades i n this standard. The ful l list of designations is: Fe 3 1 0·0 Fe 360 B, B F U, B F N , C, D 1 , D2 Fe 430 B, C, D 1 , D2 Fe 510 B, C, D 1 , D2, D D 1 , DD2 Fe 490·2, Fe 590-2, Fe 690·2 Fe 360 A, Fe 430 A, Fe 510 A (see an nex D)

This European Standard specifies six qual ities: 0, B , C, D, D D and 2. Products of qua lity D and DD are subd ivided into two qual ities 01, D2, D D1 and DD2 (see 7.2). Steels of qualities 0, 2 and B are base steels, unless a suitabil ity for cold forming is specified. Steels of qualities C, D1, D2, D D1 and DD2 are quality steels. The qualities differ in weldability and specified im pact values (see also 7 .5.1). 6.2 Designation*

6.2.1 The designation of the steels is as specified in

EU RONO R M 27 (1974 ) . NOTE 1: For a list o f corresponding formar national designations see annex C, table 10. NOTE 2: In this European Standard the old designation from EURONORM 25 (1 972) based on tensile strength Is used, This is done because at the time of publication of this European Standard the transformation of EURONORM 27 (1974) into a European Standard was not completed.

If other elements are used they sha l l be reported in the inspection document.

7 .2 Delivery conditions 7 .2.1 General

If an inspection document is required (see 8.1.2) and products are ordered and delivered in the condition N this shall be indicated in the document.

6.2.2 The designation consists of:

The number of this European Standard. - The symbol Fe. The indication of the m inimum specified tensile strength for thicknesses< 3 mm expressed in N/mm 2• The qua I ity designation (see 6.1) in respect to the weldabi lity and specified impact values. If applicable (for Fe 360 B), a letter com bination for the deoxidation method ( F U or F N ) (see 7.1.3). If appl icable, the letter combination for the suitabi lity for the particu lar appl ication (see table 6). If applicable, the letter N when the products sha l l be de livered in the condition N (see clause 3) (not necessary for flat products of qualities D1 and D D1 ) .

NOTE: Stress relief annealing at more than 580 C or for over 1 hour may lead to a deterioration of the mechanical properties . If the purchaser Intends to stress relief anneal the products at higher temperatures or for longer times the minimum values of the mechanical properties after such a treatment should be agreed at the time of the enquiry and o rde r .

7.4.2 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). 7.4.3 For flat products of quality D 1 and DD1 supplied as-rolled for norm alizing by the purchaser the samples shall be normalized. The values obtained from the normalized samples shall com ply with this European Standard. NOTE: The results of these tests do not represent the properties of

the supplied products but indicate the properties which may be achieved after correct normalizing.

I mpact tests are not required for nominal thickness <6 mm. For products of quality D 1 , D2, D D 1 and D D2 with nominal thickness< 6 mm the ferritic grain size shall be � 6, verified by the method as described in EU RONORM 1 03*, if specified at the time of enquiry and order. O ption 6. When aluminium is used as the grain refining element, the grain size requirement shall be deemed to be fulfilled if on ladle analysis the aluminium content is not less than 0,020 % total aluminium or alternatively, 0,0 1 5 % acid soluble aluminium. I n this case verification of the grain size is not required. 7.4.5 The impact properties of quality B products are verified by test only when specified at the time of the enquiry and order. Option 7 .

7.5.11 We/dability

7.5.11.1 The steels specified in this European Standard do not have unlimited suitability for the various welding prociesses, since the behaviour of a steel during and after weld ing depends not only on the material but also on the dime1nsions and shape and on the manufacturing and service conditions of the components.

7.5.11.2 There is no information concerning the weldability of the qualities 0 and 2 available as no requirements are specified concerning the chemical composition. 7.5.11.3 Steels of the qualities 8, C, 01, D2, D D 1 and DD2 are generally suitable for welding, by all welding processes.

The weldability increases for each grade from quality B to D D. For IFe 360 B killed steels are preferable to rimmed steels particularly if segregation zones could be encountered during welding. NOTE 1: With increasing product thickness, increasing strength level and increasing carbon equivalent value the occurrence of cold crack ing in the welded zone forms the main risk. Cold cracking is caused by the fol l owing factors in combination: the amount of diffusible hydrogen in the weld metal - a brittle structure of the heat affected zone - sil�nlficant tensile stress concentrations in the welded joint. NOTE 2: When using reco mmendations as laid down, for example in Information Circular Number 2 or any relevant national standard, the rncommended welding conditions and the various welding ranges of the steel grades can be determined depending on the product thickness, the applied welding energy, the design require ments, the electrode efficiency, the welding process and the weld metal propert ies.

Hot forming

Only products ordered and supplied in the normalized or normalized rolled condition shall comply with the require ments of tables 4 and 5 if hot forming is carried out after deliv1ery (see 7.4.1).
