OSNA®-10 and OSNA®-30kme_logo 4c_pc4 (pantone 032C)

The sea and its atmosphere is one of the most corrosive environments on the earth. Seagoing vessels need large amounts of seawater daily for

> fire water systems
> sprinkler systems
> cooling systems
> ballast systems

The materials used for seawater piping systems therefore must be highly resistant to cavitation erosion, crevice and galvanic corrosion as well as stress corrosion cracking. Moreover such materials must satisfy high standards in terms of hot and cold working properties and weldability
