Thermal and surface treatments
All our wire rods can be supplied with thermal and/or surface treatments with different finishes.
Every process begins with the passage of the wire rod through a stripping line (chemical stripping or shot blasting). In it, the iron oxide (Fe2O3) that is formed in the hot rolling of the wire rod is cleaned and it is given a surface coating suitable for its subsequent deformation.
Annealing is used as a heat treatment, in order to regenerate the structure of the steel and, at the same time, give the material certain mechanical and structural characteristics.

Annealing
Annealing is carried out in an EBNER furnace with a H2/N2 hydrogen atmosphere, following specific processes depending on the type of steel.
The wire rod, before being annealed, is subjected to chemical pickling or shot peening; This means that, in its subsequent use, there is no problem of removing calamine.
