BS EN 10028-6:2009

A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the Wn Centre has the same status as the official versions. 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of an identical text or by endorsement, at the latest by Decemberand conflicting national standards shall be withdrawn at the latest by December This document supersedes EN For relationship with EU Directive ssee informative annex ZA, which is an integral part of this document.

This European Standard consists of the following parts, under the general title Flat products made of steels for pressure purposes: General requirements Part 2: Non-alloy and alloy steels with specified elevated temperature properties Part 3: Weldable fine grain steels, normalized Part 4: Nickel alloy steels with specified low temperature properties Part 5: Weldable fine grain steels, thermomechanically rolled Part 6: Weldable fine grain steels, quenched and tempered Part 7: This document includes a Bibliography.


The requirements in EN also apply. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments 10028- or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

For undated references the latest edition of the publication referred to applies including amendments.

Q ; b series with elevated temperature properties P Additionally the relevant options of EN apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification see also EN B or 10 plates — 50 x 2 x 10 — EN 1.

NOTE 1 With increasing product thickness and strength level cold cracking can occur. Cold cracking is caused by the following factors in combination: NOTE 2 When using recommendations as laid down, for example in EN and ENthe recommended 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 requirements, the electrode efficiency, the welding process and the weld metal properties.

It is therefore recommended that the purchaser seeks, at 100286- time of enquiry and order, the advise of the manufacturer and considers, where appropriate, the verification of the mechanical dn on simulated post weld heat treated samples. For possible verification of internal soundness, see also EN For the impact test, deviating from EN In this case, test temperatures and minimum impact energy values shall also be agreed.


EN – Flat products made of steels for pressure purposes – Part 6: –

All appropriate measures shall be taken to prevent the addition from scrap and other materials used in steelmaking of these elements which may 1002-86 affect the mechanical properties and usability. The chemical composition range for each manufacturer’s analysis shall be given in the offer and confirmation of order. For reasons of hot formability, rn lower copper content and a maximum tin content may be agreed at the time of enquiry and order.

Aluminium is also included in these elements.

Other product thicknesses may be agreed at the time of enquiry and order. An agreement at the time of enquiry and order shall be reached on this between the purchaser and manufacturer. If agreed at the time of enquiry and order, these values also apply to the grades P QL with specified low temperature properties.

Once this standard is cited in the Official Journal of the European Communities under that Directive and has been implemented as a national standard in at least one Member State, compliance with the clauses of this standard given in table ZA. Other requirements and other EU Directives may be applicable to the product s falling within the scope of this standard.
