DC03 AM FCE: Premium Cold Rolled Mild Steel for Superior Formability

DC03 AM FCE is a cold rolled non-alloyed mild steel grades with guaranteed maximum yield and tensile strength, guaranteed minimum ductility (elongation at fracture) and good formability (n and r values). These grades comply with the requirements of the EN 10130:2006 standard and are obtained after either batch or continuous annealing. This steel grade has excellent formability, which facilitates cold forming operations, and are ideal for deep drawing. This steel for cold forming also offer excellent forming performance, due to the low scattering of their chemical composition and their mechanical properties, which guarantees processing consistency.

Technological properties

Property
Application areas	Used for bending and deep drawing forming processes for applications where strength, rigidity and ductility are required. Typical applications are to be found in the automotive industry, the domestic appliance sector, metal furniture, drums, radiators, fans, small welded tubes and small profiles. Uncoated cold rolled steels for cold forming are suitable for food contact, under certain conditions laid down in the Regulation (EC) No. 1935/2004 and the French standard NF A 36-714. Please contact us for further information on this subject.
Coating	Galvanisation: Class 1
Surface Finish	This grade is available in: A: for non-visible parts B: for visible parts
Surface condition	Surface cleanliness If improved surface cleanliness is required, ArcelorMittal also offers with compulsory use of hydrogen annealing.
Welding	Weldability is guaranteed when using the usual processes. Please specify which process you intend to use when ordering.
Workability	ArcelorMittal steel grade DC03 for cold forming have excellent drawability in all types of forming processes. They can be used to manufacture complex, multifunctional parts, and allow significant savings. Forming limit curves can be used to define the maximum strains not to be exceeded when forming steel by various methods, so as to avoid the risk of incipient necking. These curves are available on request.
