UNS S32550 : Super Duplex : A276 (VO1.03), A479 (VO1.03)
Trade Name Ferralium Alloy 255 (5)
The characteristic features of high strength and corrosion resistance exhibited by the dual microstructure (austenite, ferrite) associated with duplex stainless steels are found in UNS S32550. It is similar in composition to the more widely used super duplex grade UNS S32760. UNS S32550 has a slightly higher copper level, lower nickel and no deliberate tungsten additions, and is normally supplied to achieve the UNS S32760 PREN requirement of 40.
Condition: Solution Annealed and Water Quenched.
