Properties

These grades are characterised by their hardness after heat treatment. They can offer high strength ratings, including fatigue resistance.

Advantages

High carbon and alloy steels are designed for the production of parts for intensive use.

Applications

They can be cold rolled and subjected to heat treatment (quenching and annealing), depending on their intended application, and are used to make mechanical parts, such as clutches, springs, segments, saw blades, measuring tape etc.

Technical properties

Thickness tolerance

In view of the tolerance values required for finished products made from narrow strip, ArcelorMittal normally offers a tighter tolerance range for these grades (half the tolerance range required by the EN 10051:2010 standard).

 

Transverse coil profile

As these products are frequently re-rolled after slitting, ArcelorMittal can supply coils with an extra flat profile (to order), which can guarantee a hot-rolled strip crown lower than 60 µm for coil thicknesses ranging from 2 to 6 mm.

Do not hesitate to contact us.

 

Internal purity

Our steels have the degree of internal purity corresponding to the steel grade specified. It is possible to agree on the required degree of purity at the time of enquiry and order.

 

Decarburisation

The guaranteed maximum decarburisation is 2% (sum of the decarburisation measured on the two sides).

Heat treatment

As these steel grades generally undergo heat treatment, a number of diagrams showing typical behaviour are available on request, such as:

 

As an example, here is a CCT diagram for the C75S AM FCE grade.
