These steels are employed in the mechanical and petrochemical fields, principally in power stations. They are used for equipment that must function at a temperature of over 350° C. The plastic deformation due to the viscose creep is the result of the combined action of temperature-stress-time. Our controlled casting and rolling practices enable us to achieve a perfect ferrite structure hardening, higher micro-purity and controlled austenitic grain.

Production takes place in a rolling mill at a controlled temperature using the very latest technology which guarantees a fine grain and homogeneous structure; the calibrator finishing block allows bars with restricted dimensional tolerances.
