EN 10025-5:2004 (E)

7.3.1.2 For products ordered and supplied in the normalized or normalized rolled condition (see 6.3) the

mechanical properties shall comply with Tables 4 and 5 in the normalized or normalized rolled condition as well as after normalizing by heat treatment after delivery.

7.3.1.3 For products of quality J2 and K2 supplied as-rolled for normalizing by the purchaser the samples shall be normalized, if requested at the time of the order. The values obtained from the normalized samples shall comply with this document. The results shall be reported in the inspection document. See option 19b (deals with +AR).

NOTE The results of these tests do not represent the properties of the supplied products but indicate the properties which can be achieved after correct normalizing.

7.3.1.4 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 of EN 10025-1:2004). 7.3.2 Impact properties 7.3.2.1 7.3.2.2 the order.

The verification of the impact energy value shall be carried out in accordance with EN 10025-1. The impact properties of steel grade S355 class WP are verified only when specified at the time of

See option 3.

7.3.2.3 For products of quality J2 and K2 with nominal thickness < 6 mm the ferritic grain size shall be ≥ 6, verified by the method as described in EN ISO 643, if specified at the time of the order. See option 21.

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, 0,015 % acid soluble aluminium. In this case verification of the grain size is not required, but the aluminium content shall be indicated in the inspection document.

7.3.3 Improved deformation properties perpendicular to the surface

If agreed at the time of the order products of qualities J2 and K2 shall comply with one of the requirements of EN 10164. See option 4.

7.4 Technological properties

7.4.1 Weldability

7.4.1.1 The steels specified in this document do not have unlimited suitability for the various welding processes, since the behaviour of a steel during and after welding depends not only on the material but also on the dimensions and shape and on the manufacturing and service conditions of the components. 7.4.1.2

In Annex D more information on weldability may be found.

7.4.2 Formability 7.4.2.1 General

NOTE Recommendations regarding hot and cold forming are laid down in ECSC IC 2. Although ECSC IC2 is specially meant for fine grain steels, these recommendations can also apply for the steel grades of EN 10025-5.
