15Cr-5Ni duplex stainless steel is a two-phase ferritic-austenitic stainless alloy with elevated cobalt and silicon content, positioned as a high-strength variant within the duplex family. The dual-phase microstructure delivers an attractive combination of strength and ductility while maintaining corrosion resistance superior to ferritic grades. This composition is suited for demanding structural and wear-resistant applications where engineers need to balance load-carrying capacity with environmental durability, particularly in moderately corrosive or abrasive service conditions.
