S32900 Duplex Stainless Steel Round Bar & Super Duplex Stainless Steel Round Bar:

Duplex alloys were originally created to combat corrosion problems caused by chloride - bearing cooling waters and other aggressive chemical process fluids. Called Duplex because of its mixed micro - structure with about equal proportions of ferrite and austenite, duplex stainless steels are a family of grades, which range in corrosion performance depending on their alloy content. The chemical composition based on high contents of Cr and Mo, improves intergranular and pitting corrosion resistance, respectively. Additions of nitrogen can promote structural hardening by interstitial solid solution mechanism, which raises the yield strength and ultimate strength values without impairing toughness. Moreover, the two - phase micro - structure guarantees higher resistance to pitting and stress corrosion cracking in comparison with conventional stainless steels.
