  Steels for cold forming   Last update: 2011-4-5

These steels can be used to manufacture multifunctional and complex parts, like this radiator.

 

Properties
   

This is a range of 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.

 

Advantages
   

These steel grades have excellent formability, which facilitates cold forming operations, and are ideal for deep drawing.

ArcelorMittal's range of steels for cold forming offer excellent forming performance, due to the low scattering of their chemical composition and their mechanical properties, which guarantees processing consistency.

 

Applications
   

They are 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, tubes and small profiles. Uncoated cold rolled steels for cold forming are suitable for food contact, under certain conditions laid down in directive 89/109/EEC and the French standard NF A 36-714. Please contact us for further information on this subject.

 

Surface quality
   

Surface appearance

ArcelorMittal offers two types of surface quality for these grades:

  • A: for non-visible parts
  • B: for visible parts

 

Surface roughness

A wide range of roughness levels according to the EN 10130 standard can be supplied. Unless otherwise specified when ordering, coils will be supplied with standard roughness (0.6 Ám < Ra < 1.9 Ám).

 

Formability
   

ArcelorMittal steels for cold forming (grades DC03 to DC07) have good or even 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.

 

Weldability
   

Weldability is guaranteed when using the usual processes. Please specify which process you intend to use when ordering.

 

Fatigue resistance
   

Fatigue resistance is generally expressed as an endurance limit, corresponding to the maximum stress resisted for a given number of cycles before failure. The table below gives some examples of 5 million cycle endurance limits under fluctuating tension with a stress ratio Rs = 0.1.

A complete database of fatigue resistance data on this range of steels is available on request.
