Stainless steels

Stainless steel is the most highly adapted material to resist stress conditions and corrosion resistance typical of chemical and petrochemical processes.

The use of stainless steel is mainly focused on offshore drilling platforms, mostly due to the severe corrosive conditions to which they are exposed.

Valbruna’s production of Stainless steel, Duplex and Superduplex, is certified according to Norsok/Statoil M650.
