Hot rolled laminate for structural uses

Structural steels are suitable for structural uses by exhibiting various technological properties such as welding, formability, bending, hot-dip galvanizing and machinability.

"Black" hot rolled laminate - with a rough rolling surface, so called because of the presence of calamine - is available. Calamine is an oxide layer that characterizes the coloring and protects the material from weathering.

+AR	LAMINATE: Term of delivery without a special rolling and/or heat treatment condition
+N	NORMALIZATION LAMINATION: Rolling process in which final deformation is carried out in a given temperature range capable of developing a material with conditions equivalent to those obtained after normalization treatment, so that the prescribed values for mechanical properties remain in place after normalization treatment
+M	THERMOMECHANICAL LAMINATION: Rolling process in which the final deformation is carried out in a specific temperature range capable of developing a material condition with certain properties that cannot be obtained or repeated by heat treatment alone. (also referred to as TMCP)

(a) Test effected transverse (t) to the rolling direction.
(b) Test effected parallel (l) to the rolling direction.
(c) s = thickness of the laminate in mm
For plates, strips, and wide plates with widths ≥600 mm, transverse (t) to the rolling direction is applied. For all other products, the values for the direction parallel (l) to the rolling direction apply.
