              Super Duplex UNS S32760 Stainless Steel Bar

               

              Super Duplex UNS S32760 is very similar to 32750 with slight differences in their chemical compositions. 32760 contains lower amounts of manganese, phosphorus, sulfur, molybdenum and nitrogen; conversely it has higher amounts of silicon and copper. However, the chemical makeup of both grades requires identical amounts of carbon, chromium, and nickel; making them interchangeable for some applications.

              UNS S32760 is able to compete strongly with the 6% molybdenum “super austenitic” grades in some applications, as it has fewer amounts of Mo and Ni which drive up the base cost of the material. Although, 32760 has lower amounts when compared to “6% Moly” grades it still has higher contents of Cr, Ni, and Mo when referring to other alloys, these elements improve the intergranular and pitting corrosion resistance of the material. The specific addition of nitrogen promotes structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. The two phase “duplex” microstructure guarantees higher resistance to pitting, stress corrosion cracking, corrosion fatigue, crevice corrosion and strong weldability in comparison with conventional stainless steels.
