  Structural forming grades   Last update: 2011-4-5

These steels are recommended when high reproducibility of processing performance is required.

 

Properties
   

ArcelorMittal's structural forming grades offer superior strength compared with standard deep drawing grades. Furthermore, their mechanical properties meet very narrow tolerance limits.

 

Advantages
   

S200 AM FCE is the basic grade in the range and corresponds to DD11 (EN 10111:2008).

S200D AM FCE, which corresponds to DD14 (EN 10111:2008), is recommended for extreme deep drawing operations.

S240D AM FCE offers mechanical properties equivalent to those of DD11 (EN 10111:2008), and a strength corresponding to S235JR (EN 10025-2:2004).

 

Applications
   

Structural forming grades are well suited to applications requiring high reproducibility of processing performance (especially control of springback). That is why the S200D AM FCE grade is especially suitable for applications such as compressor casings. The S240D AM FCE grade is popular with Steel Service Centres, since it allows them to rationalise their supplies of deep drawable and structural steel. This grade is a versatile material for numerous applications in industry markets.
