Alpha Overseas(AOS) is one of the prominent suppliers that offer Super Duplex Ferralium 255 Flanges, which in addition has good chemical corrosion resistance as well as being erosion resistant. Ferralium 255 Pipe Flanges is called as "super", because it is more alloyed than ordinary stainless steels and has superior corrosion resistance. Ferralium 255 Slip On Flanges achieves higher strengths than other alternative corrosion resistant alloys, offering the potential to reduce section size and therefore weight and cost. This cost effective Ferralium 255 Blind Flanges has a number of beneficial characteristics including: resistance to corrosion, crevice corrosion, pitting, and chloride stress corrosion cracking. Ferralium 255 Socket Weld Flanges has great ductility and impact strength at both ambient and sub-zero temperatures. This combination makes Ferralium 255 Weld Neck Flanges ideal for demanding applications in a number of different industries such as Offshore, Pulp & Paper, Oil & Gas, Nuclear, Chemical Processing, Flue Gas Desulfurization and Marine Industry. In seawater and other chloride containing environments, Ferralium 255 Orifice Flanges also provides outstanding resistance to pitting and crevice corrosion, with Critical Pitting Temperature exceeding 50 Degree C.
Ferralium 255 Ring Type Joint Flanges are characterised by higher Chromium content than standard duplex stainless, typically around 25 % and offer improved corrosion resistance and better mechanical properties. We have been recognized for our outstanding customer service to offer F255 Flanges, in satisfaction surveys of top-ranked mills in India and all over the world.
Our products are made from superior quality Raw Material and are available in Customized Designs to suit different requirements of the clients. Our contemporary technology and constant efforts to acquire new skills to enhance production is the secret of our success and impeccable quality.
