Duplex Stainless Steels have a mixed microstructure of austenite and ferrite, the aim usually being to produce a 50/50 mix, although in commercial alloys the ratio may be 40/60. Gujarat Ferro Alloys Pvt Ltd is an ISO 9001:2008 awarded company that manufactures Duplex Stainless Steels.
Gujarat Ferro Alloys Pvt Ltd also manufactures wide range of metal castings such as Steel, Stainless Steel, Cast Iron, SG Iron, Manganese Steel and Aluminium. Duplex Stainless Steels have twice the strength compared to austenitic stainless steels and also improved resistance to localized corrosion, particularly pitting, crevice corrosion and stress corrosion cracking. They are characterized by high chromium [19–28%] and molybdenum [up to 5%] and lower nickel contents than austenitic stainless steels. Duplex grades are characterized into groups based on their alloy content.
