  Steels with guaranteed mechanical properties   Last update: 2011-4-5

These grades are especially recommended for forming by bending or profiling, for furniture, shelving etc.

 

Properties
   

These cold rolled thin steels are obtained by continuous annealing, which gives them very good surface purity, excellent uniformity of their mechanical properties and a high standard of flatness. HC180CA AM FCE grade complies with the EN 10130:2006 standard for DC01.

 

Advantages
   

The excellent properties of these steels allow smooth and continuous operation of the various process steps, which is particularly important on high productivity automated lines. These grades are especially recommended for forming by bending or profiling.

 

Applications
   

These steels are used for the manufacture of casing panels for domestic appliances, heating equipment, furniture, shelving, drums etc.

 

Recommendations for use
   

The weldability of these cold rolled grades using conventional processes is guaranteed. Nevertheless, it is recommended that the welding process should be specified when ordering.

These grades are also suitable substrates for coatings such as phosphating, painting, electroplating and hot dip galvanisation.

 

Surface quality
   

These cold rolled steels are available with surface types A or B as defined in the EN 10130 standard.
