Austenitic Outokumpu Supra 316plus (EN 1.4420, ASTM UNS S31655) is designed for highly corrosive environments. Its high chromium and nitrogen content delivers improved corrosion resistance. The grade has high strength, good formability and excellent weldability. Supra 316plus works extremely well for challenging conditions.
Supra 316plus enables lighter structures, that, in turn, can allow increased transport load volumes resulting in a decreased total number of transports needed. These factors can even reduce the fuel consumption, thus Supra 316plus leaving a lower a carbon footprint.
The high chromium content makes the Supra 316plus appropriate for replacing standard grades in many applications. Supra 316plus is ideal for a variety of applications including LNG, tank containers, heat exchangers, water treatment and tubular projects. The grade also works well in architectural applications.
