State-of-the-art production equipment, a highly qualified team of engineers and operators rigorously implementing a DNV-certified quality system guarantee the highest standard of quality and service of the most demanding users.

Lucchini RS’s long experience in high-grade steels has enabled it to develop a range of tool steels for plastic moulding and ferrous and non-ferrous hot-working processes, such as extrusion, moulding, die-casting and gravity casting.

Steel is produced with rigorous manufacturing and control cycles, in various states of heat treatment and surface finish, in accordance with the main supply specifications or to the customer’s specifications. For special applications requiring an exceptionally pure ingot with virtually no shrinkage micro-cavities, the steel undergoes further refinement in an electro slag remelting plant (ESR).
