Sandvik has achieved NORSOK® certification for its duplex and new super-duplex solid bar, opening up greater application opportunities as they meet the exacting demands and standards of the oil & gas industry.
Extensive work by Sandvik has resulted in the new NORSOK® M-630, Edition 6 accreditation being secured for duplex solid bar grades Sandvik SAF 2205™ and Sandvik SAF 2507™. The difference is that Sandvik takes two samples of the material from different locations in order to test and verify the microstructure. In addition, the second sample is taken from the centre of the material to ensure homogeneity. This consistency of material characteristics makes for a more dependable product.
NORSOK® approval has also been achieved for a new super-duplex grade, Sandvik SAF 32760™, which offers excellent corrosion resistance and high mechanical strength. Its use facilitates the manufacture of lighter components and more compact system designs with less welding. The material grade provides significant advantages in component manufacture particularly for oil and gas and subsea applications. Similarly, it can be used for components in chemical processing, pulp and paper, refineries and marine applications as well as in desalination plant.
