Duplex Steel Stub End
High strength combined with excellent corrosion resistance
Duplex Pipes Fitting 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 Pipes Fitting in UNS S31803 (2205) and S32205 grades for offshore, marine and chemical process piping where both strength and corrosion resistance are critical.
