Certified Manufacturer & Exporter of Super Duplex S32760 Pipe Fittings in India
Kalpataru Piping Solution is a well-known exporting unit of Super Duplex Steel UNS S32750 Pipe Fittings / Super Duplex Steel S32760 Pipe Fittings, which is moderately ductile and forms effortlessly. Meanwhile, Kalpataru Piping is a leading exporter of Super Duplex Steel UNS S32750 and S32760 Pipe Fittings, manufactured under ASTM A815 / ASME SA815 standards. These fittings combine a duplex austenite-ferrite microstructure, delivering approximately twice the yield strength of standard austenitic stainless steels. Their high chromium (24–26%), molybdenum (3–5%), and nitrogen content provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive chloride and sulphide-rich environments. UNS S32750 and S32760 fittings are engineered for demanding service conditions including offshore oil and gas platforms, desalination plants, and chemical processing units. With a Pitting Resistance Equivalent Number (PREN) exceeding 40, they outperform standard 316L and duplex 2205 grades in environments with high chloride concentrations, acidic media, and elevated temperatures. S32760 includes additional copper and tungsten, making it the preferred choice for the most aggressive process environments.
