NOTE 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.

Coil EN 10268-HC220B-B-m or Coil EN 10268-1.0396-B-m. 5 Requirements 5.1 Steelmaking
and manufacturing processes Unless otherwise agreed at the time of enquiry or order, the steelmaking and manufacturing processes are left to the discretion of the manufacturer. If specified by the purchaser, he or she will be informed of these processes. 5.2 Chemical composition The chemical composition based on the ladle analysis shall be as given in Table 1. 5.3 Delivery conditions 5.3.1 The products are supplied in the skin-passed condition only. 5.3.2 Usually the products are supplied oiled. In this case, both sides are corrosion protected by a layer of neutral non-drying oil, free of impurities and uniformly spread so that under the normal packing, transportation, loading and storage conditions, there will be no corrosion for up to three months. The layer of oils shall be capable of being removed by alkaline solutions or usual solvents. The choice of protective oils may be subject to a special agreement.
