Nuclear
For the nuclear sector, we are able to offer many Stainless steels corrosion resistant grades, Nickel and Titanium alloys for special applications in the most severe condition of the plant. Their special applications go from the system and circuits subjugated to the reactor for the steam generators, through guide-tubes, up to turbines linked to the generators. Valbruna is currently working according to the ASME and RCC-M codes, which are the most world-wide known quality and safety standards in the nuclear market.
Valbruna is a very active part in the ITER project with regards to round & square bars in 316LN-IG both for Cover Plates and Vacuum Vessel, as well as to XM-19 for Bolts & Fasteners.
Valbruna is currently facing a qualification process with EDF to become a RCC-M bars producer & distributor.
