This European Standard shall be given the s

It was asked to actualise the normative references and to bring the text in line with “Iron and steel standardization Model for
19、a product standard”. In the scope the product thickness is increased to 400 mm to be in line with EN 10025-2. The upper yield strength is increased to 960 MPa to be in line with EN 10025-6. This document includes a Bibliography. According to the CEN/CENELEC Internal Regulations, the national standar

EN 10164:2004 (E) 4 Introduction Flat products and sections of steel as normally manufactured have deformation properties perpendicular to the surface (through thickness) which are different from those obtained in the surface direction.
22、This anisotropy of the properties may lead to difficulties in welded structures, for instance lamellar tearing. It is, however, possible to improve the through thickness properties by using additional steel making procedures. Through thickness properties are characterized in this document by specifi
23、ed values for reduction of area in a through thickness tensile test. There is no direct relationship between these values and the integrity of structures, because the risk of lamellar tearing is also basically influenced by the type of structure, weld design and welding procedure. The minimum values
24、 for reduction of area in this document cannot therefore by themselves be regarded as ensuring safety against occurrence of lamellar tearing. However the reduction of area is a good general guide to lamellar tear resistance i.e. the risk of lamellar tearing decreases with increased reduction of area
25、 in the through thickness tensile test. EN 10164:2004 (E) 5 1 Scope This document specifies through thickness properties and associated test methods for flat products and sections of steel. This document may be applied as a supplement to all product standards for flat products and sections of fully
26、killed steels, except stainless steels.

33、shall refer back to the purchaser. 4.2 Options A number of options are specified in Clause 11. In the event that the purchaser does not indicate his wish to implement any of these options, the supplier shall supply in accordance with the basic specification. 5 Requirements 5.1 Reduction of area Tabl

NOTE Reduction of area (Z) is defined in EN 10002-1 as: 100 o u o S S Swhere S o is the original cross-sectional area of the parallel length; S u is the minimum cross-sectional area after fracture. For flat products th
35、e minimum values for reduction of area apply to the whole product. For sections the minimum values for reduction of area apply to either the flange or the web depending on where the samples are taken (see 7.1.1.3).
