Duplex & Super Duplex Steel Socket Weld Half Coupling
High strength combined with excellent corrosion resistance
Duplex and Super Duplex Forged Fittings are manufactured from a dual-phase stainless steel that combines austenitic and ferritic microstructures, giving the material significantly higher strength than standard stainless steel along with strong resistance to stress corrosion cracking and chloride attack.
Royal Steel India manufactures Duplex and Super Duplex Forged Fittings in UNS S31803 (2205) and S32750 grades for offshore, marine and chemical process piping where both strength and corrosion resistance are critical.
