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 | ||||||||||
