Rated in the highest corrosion resistance class by EN 1993-1-1:2006/A1:2015 (CRC V), it offers the highest atmospheric corrosion (C5) and wood (T5) resistance.
Austenitic stainless steel. It is characterised by its high molybdenum and nickel content for maximum corrosion resistance, while the presence of nitrogen ensures excellent mechanical performance.
The chemical composition, in particular the high nickel and molybdenum content, confers strength to chloride pitting and, hence, stress corrosion cracking. This is the reason why it is the only category of stainless steel suitable for use in indoor swimming pools according to Eurocode 3.
