Duplex stainless steel combines an austenitic and ferritic structure, which provides high mechanical strength and good resistance to stress corrosion in aggressive or chloride-containing environments. In even more demanding conditions, superduplex offers added reliability with exceptional corrosion resistance and load-bearing capacity. Discover below the duplex and superduplex materials that Hetraco supplies for industries such as offshore, chemical, and process industries, including custom products and small production runs.
Duplex and superduplex stainless steel are high-quality material choices for industrial applications where corrosion resistance, strength, and delivery reliability are critical. Especially in sectors such as equipment manufacturing, energy, offshore, chemicals, and the process industry, choosing the right materials is essential to prevent downtime, failure costs, and delays. Contact Hetraco to learn more about the options available for duplex and superduplex stainless steel components.
Key Properties of Duplex and Superduplex Stainless Steel
Duplex stainless steel combines an austenitic and a ferritic structure. As a result, duplex steel offers properties such as high mechanical strength, good resistance to stress corrosion, and excellent performance in chloride-containing or corrosive environments. In even more demanding conditions, super duplex steel offers added reliability. Super duplex stainless steel is often used when extreme corrosion resistance, high strength, and long-term reliability are required.
