  Steels for cold forming and deep drawing applications   Last update: 2011-4-5

The excellent deep drawing performance of these steels makes them suitable for a very wide range of applications.

 

Properties
   

Steels for cold forming and deep drawing applications are characterised by guaranteed maximum yield and tensile strength and minimum elongation.

 

Advantages
   

Steels for cold forming and deep drawing applications are available for normal (DD11 AM FCE) to very demanding (DD14 AM FCE) forming applications. ArcelorMittal also offers DD15 AM FCE grade with forming characteristics superior to those prescribed by the standard EN 10111:2008. In addition, ArcelorMittal provides guarantees for thicknesses greater than 11 mm.

 

Applications
   

This range of steel grades for cold forming is widely used for bending and drawing applications in general industry, building, the automotive industry and related sectors (e.g. oil sumps for industrial vehicles etc).

ArcelorMittal's steels for cold forming and deep drawing applications display good or even excellent performance in all types of deep drawing processes, enabling the production of complex parts.

Uncoated hot rolled steels for bending and deep drawing applications are suitable under certain conditions for food contact, as specified in directive 89/109/EEC and French standard NF A 36-714. Please contact us for further information on this subject.

 

Weldability
   

The weldability (spot and arc welding) of ArcelorMittal's hot rolled steels for cold forming and deep drawing is equivalent to that of cold rolled steels of corresponding grades. For instance, the spot weldability of DD14 AM FCE grade (thickness 2.5 mm) ranges from 9.6 to 12.6 kA.
