Preparation shall be carried out in such a way that any alteration of the surface hardness is minimized. The details of the heat treatment shall be given in the inspection document. It is fundamental that heat treatment is carried out in the best way, so that a correct micro-structure and relative mechanical 100833-3 can be obtained.

This document supersedes EN Previously, the three parts were divided up as follows: Shearable in the untreated condition. It is important to know the Jominy curve of the steel that you would like to employ. If specific testing is ordered, it shall also be agreed whether this grain size requirement is to be verified by determining the aluminium content or micrographically.

Technical 10803-3 conditions for alloy steels Aciers pour trempe et revenu - Partie 3: NOTE Depending on the product shape and dimensions, not all steel grades can be delivered in the hot worked untreated condition e. In the case of bars and rods, the sample to be quenched and tempered shall, unless otherwise agreed, have the cross-section of the product. NOTE 1 The requirements for non metallic inclusion content apply in every case, however, verification requires a special agreement.

If the order does not contain any specification of this type, a test report shall be issued. For the steel grades covered by this document, the steel names as given in the relevant tables are allocated in accordance with EN All reasonable precautions shall be taken to prevent the addition of such elements from scrap or other material used in the manufacture which affect the 110083-3, mechanical properties and applicability. Technical delivery conditions for unalloyed quality steels EN Other quenching agents enn as synthetic quenchants may also be used.

The chemical composition determined by cast analysis ne comply with the values in Table 3. Bars and rods are delivered with surface class A according to EN unless otherwise agreed at the time of enquiry and order.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CEN member. The requirement given ne Table 1, Footnote a mechanical properties of reference test piecesis only to be verified if supplementary requirement A. Steels Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality.

For verification see A. Technical delivery conditions for non-alloy steels Part 3: The depth of decarburization shall be determined in accordance with the micrographic method specified in EN ISO The values are not applicable to slabs which have been continuously cast and not further deformed.

However, the temperatures specified for the end quench test are mandatory. Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality.

When tested 100833-3 accordance with EN ISOthe steel shall have an austenite grain size of 5 or finer. The test pieces shall, unless otherwise agreed, be taken in accordance with EN
