Duplex steel S31803 coil/slitting coils offer a unique combination of advantages, including high strength and good corrosion resistance, especially against pitting, crack corrosion and stress corrosion cracking Their dual phase design ensures good mechanical properties, e.g higher tensile and yield strengths compared to austenitic steels reduce them in good weldability and formability, and provide they are suitable for complex applications. Furthermore, their high fatigue and corrosion resistance makes them durable in harsh environments, such as chemical manufacturing, marine, and oil and gas industries, and allows them to use time long and reliable.
