Sheets and broad plates of non alloyed steel for structural uses

(EN 10025 1-2-5)

Delivered
BLACK-DRY

These steels are widely used in the field of mechanical construction, especially in heavy welded structural work, in the building industry, in transport and in many other applications linked with the construction of machine tools.
For these reasons this is the most important category of construction steels.
They are generally installed without heat treatment, that is in their untreated rolled state, or at most after simple normalisation.

Deliverable grades of steel

S355JOW / S355JOWP bearing the CE mark

Hardened and tempered sheets and broad plates with a high yield quality for structural uses

(EN 10025 1-6)

Delivered
BLACK-DRY

These steels possess high mechanical strength (in particular a high elastic limit), excellent toughness, weldability and cold deformability.
These exceptional properties are obtained by means of strict control of the elements in the alloy, careful performance of the rolling process (that is a specific management of the deformation speed, the rolling temperature and the subsequent cooling) and technologically advanced heat treatments.
The strong reduction in the contents of undesirable secondary elements (such as S, P, N, H, O) and of the quantity of non metal inclusions present (and their shape), ensure extraordinary internal homogeneity of the material.
Direct hardening after hot rolling, followed by tempering (which is considered the equivalent of the conventional hardening and tempering heat treatment) guarantees uniform strength and the required high mechanical characteristics.
These materials also behave better under fatigue than traditional steels.

Thermomechanical steel sheets and broad plates with a high yield

(EN 10149 1-2-3)

Delivered
BLACK DRY

These steels possess high mechanical strength (in particular a high yield quality), excellent toughness, weldability and cold deformability.
These exceptional properties, obtained by means of strict control of the elements in the alloy and careful performance of the production processes (thermomechanical rolling), allow them to be used in fields that require high strength and low weight at the same time.

Deliverable grades of steel
S315MC / S355MC / S420MC
S460MC / S500MC / S550MC / S600MC
S650MC / S700MC / S260NC / S315NC / S355NC / S420NC

Sheets and broad plates of anti-wear / anti-abrasion steel

Delivered
BLACK-DRY

These steels possess excellent resistance to wear and mechanical abrasion, due to impact or friction.
They are also distinguished by high hardness and a very high yield quality, as well as excellent characteristics of toughness and cold formability.
These properties therefore make them more suitable than traditional steels in many applications where very high mechanical strength and resistance to wear are required.
The sheets are supplied tempered (in water) with controlled cooling.
They are totally killed and processed with a fine grain with the addition of microalloying elements such as niobium and vanadium.
These steels are “branded products”, so they are known to users by the typical name given to each one by the manufacturer.
