Vallourec's series of Oceanfit® grades is geared specifically to offshore applications where tubes are exposed to extreme environmental conditions. Besides outstanding mechanical properties and impact toughness at temperatures well below freezing point, these grades possess excellent welding properties.
Oceanfit® grades are available in three different levels of yield strength/impact toughness combinations, with yield strengths between 690 and 890 MPa and impact toughness down to -50 °C. Depending on the harshness of conditions, Oceanfit® grades can be selected to precisely match application requirements in ship construction, superstructures, jack-up rigs, platform cranes, helicopter decks and housings specifically designed for long-term resistance in challenging project environments.
1) If Cu > 0.30 %, Ni has to be at least half of Cu.
1) QT: quenched and tempered.
2) Valid for the smallest wall thickness range given in the respective material data sheets.
