BS EN 10111:2008 – Continuously hot rolled low carbon steel sheet and strip for cold forming — Technical delivery conditions
1 Scope
This European Standard specifies the grades of continuously hot rolled low carbon steel sheet and strip (in coils) for cold forming.
Depending on its actual width, strip is classified as:
hot rolled wide strip if its width is greater than or equal to 600 mm;
hot rolled slit wide strip if its width is less than 600 mm.
For each grade, it specifies the chemical composition and the mechanical properties.
This European Standard is applicable to products of thickness not less than 1 ,0 mm and not exceeding 1 1 mm.
This European Standard is not applicable to products covered by other standards, such as:
hot rolled products of non-alloy structural steels for general use (see EN 1 0025 all parts);
steel sheet for pressure purposes (see EN 1 0028 all parts);
steel sheet for welded gas cylinders (see EN 1 01 20);
quenched and tempered steels (see EN 1 0083-1 and EN 1 0083-2).

3 Terms and definitions
For the purposes of this European Standard, the terms and definitions of hot rolled flat products are those given in EN 1 0079.
4 Classification and designation
4.1 Classification
The choice of steel grade and product type is left to the purchaser. For this choice, the purchaser may be advised by the manufacturer, but without any liability on the part of the latter, unless agreed at the time of enquiry and order.
Hot rolled products are classified into four grades DD1 1 , DD1 2, DD1 3 and DD14 defined by chemical composition, mechanical and forming characteristics (see Table 1 ).
4.2 Designation
4.2.1 The steel names are in compliance with EN 1 0027-1 ; the steel numbers, with EN 1 0027-2.
4.2.2 Products conforming to this European Standard shall be designated, in order, in the following way:
a) product designation (e.g. “strip”, “sheet” or “slit strip cut longitudinally”) in line with EN 1 0079;
b) number of this European Standard (EN 1 01 1 1 );
c) symbolic or numerical designation of the steel (see Table 1 ).
