3.3 high strength interstitial free steels (Y) steels whose composition is controlled to achieve improved plastic strain ratio r and strain hardening exponent n values Note 1 to entry: These steels have both a high mechanical strength and an excellent suitability for cold forming due to their solid solution hardening and interstitial free microstructure. They are used for complex components involving deep drawing processes. 3.4 isotropic steels (I) steels with limited plastic strain ratio r value Note 1 to entry: These steels have excellent stretch formability due to their isotropic behaviour. They are used in the automotive industry for bonnets and doors." 4 Designation The steel names are in compliance with EN 10027-1; the steel numbers with EN 10027-2. The designation consists of the word "sheet", "cold rolled wide strip", "cold rolled narrow strip", "slit cold rolled wide strip " or "cut length" followed in order by:  reference to this European Standard EN 10268;  steel name or the steel number (see Table 1 or Table 2);  symbol concerning the surface quality (A or B);
 if applicable, the symbol relating to the surface finish. !EXAMPLE 1
