Stainless steel S32550 introduction :
Stainless steel S32550 is a 25% chromium duplex ferritic-austenitic stainless steel designed to provide a superior combination of high strength and excellent corrosion resistance for a wide variety of applications. The alloy possesses a microstructure which is a balanced mixture of austenite and ferrite. The combination of these phases develops the unique combination of strength and chloride stress-corrosion cracking resistance of this alloy. The alloy finds applications in marine corrosion areas, equipment for phosphoric acid and fertilizer industry, pollutions control equipment, the pulp and paper industry and the petrochemical industry.
