77.140.50 - Flat steel products and semi-products

This document specifies a method for determining the tensile strain hardening exponent n of flat
products (sheet and strip) made of metallic materials.
The method is valid only for that part of the stress-strain curve in the plastic range where the curve is
continuous and monotonic (see 8.4).
In the case of materials with a serrated stress-strain curve in the work hardening range (materials
which show the Portevin-Le Chatelier effect, e.g. AlMg-alloys), the automatic determination (linear

This document specifies a method using a barcoding system for tracing potential isolated defects that can be present in the following kinds of coated or uncoated steel flat products, for example:
-   electro-galvanised surface
-   galvanised surface
-   galvannealed surface
-   cold rolled surface
This method, named “quality tracking”, aims at transferring additional material information to the steel users, especially the location of some isolated defects, in a reliable way. This method enables the...view more

1.1   This European Standard applies to cold rolled narrow strip in coils and cut lengths in thicknesses up to 10 mm and of widths less than 600 mm, made from low carbon, unalloyed and alloyed steels in accordance with Table 1.
These products are suitable for cold forming. They are also suitable for surface coating. On the other hand, they are not suitable for hardening treatment followed by tempering.
