Ashtavinayak Alloys is a leading manufacturing, Supplying, and exporting of superior range of Duplex Steel S32304 Flanges, which made from high Quality of Standard Materials and outlined according to with national and International standard. Ferralium 255 – SD50 (super duplex 255) is a super duplex stainless steel supplied in the hot worked and annealed condition. It achieves higher strengths than most stainless steels and alternative corrosion resistant alloys, offering the potential to reduce section size and therefore weight and cost.

As a 25% Cr alloy, with significant additions of copper, Ferralium® 255 offers excellent corrosion resistance in a wide variety of corrosive chemicals including sulphuric, nitric and phosphoric acid. Copper is widely known to improve resistance to acids, and Ferralium 255 contains 2% copper, which is more than other super duplex grades. In seawater and other chloride containing environments it also provides outstanding resistance to pitting and crevice corrosion, with Critical Pitting Temperature exceeding 50°C. Excellent ductility and impact strength at both ambient and sub-zero temperatures combine with a high resistance to abrasion, erosion and cavitation erosion.
