Duplex-grade stainless steel alloys have ferritic/austenitic properties, giving these materials superior strength and excellent resistance to oxidation. While the duplex-grade family includes a wide range of specific formulations, S31803 (2205) and super duplex S32750 (2507) are two of the most common. These stainless steel products are extremely versatile, with many applications in the oil and gas, petrochemical, and chemical processing industries.
