DIN EN 10130:2007-02 Cold rolled low carbon steel flat products for cold forming – Technical delivery conditions
This European Standard applies to cold rolled uncoated low carbon steel flat products in rolled widths equal to or over 600 mm for cold forming, with a minimum thickness of 0,35 mm and, unless otherwise agreed at the time of inquiry and order, equal to or less than 3 mm, delivered in sheet, coil, slit coil, or cut lengths obtained from slit coil or sheet.
It does not apply to cold rolled narrow strip (rolling width < 600 mm) nor to flat cold rolled products for which there is a specific standard, in particular the following:
— cold rolled non-grain oriented magnetic steel sheet and strip (EN 10106);
— semi-processed steel strip for the construction of magnetic circuits (EN 10126 and EN 10165);
— blackplate in coils (EN 10205);
— cold rolled flat products in high yield strength steels for cold forming (EN 10268);
— cold rolled uncoated non-alloy mild steel narrow strip for cold forming (EN 10139);
— cold rolled low carbon steel flat products for vitreous enamelling (EN 10209).
Size:
OD 4.6-10.6mm
WT 0.35-1.0mm
Length 0.6m or according to customer's request
Application: For automobile and refrigeration industry

| a The values of yield strength are 0.2 % proof strength for products which do not present a definite yield point, and the lower yield strength ReL for the others. When the thickness is less than or equal to 0.7 mm and greater than 0.5 mm, the value for yield strength is increased by 20 MPa. For thicknesses less than or equal to 0.5 mm, the value is increased by 40 MPa. h For design purposes the lower limit of Re for grade DC06 may be assumed to be 120 MPa and | ||||||||||
