Corrosion Resistance: Duplex Steel 31803 is known for its excellent corrosion resistance, particularly in aggressive environments like seawater and chloride-containing solutions. This makes it suitable for applications where resistance to pitting, crevice corrosion, and stress corrosion cracking is essential.


Strength: It offers high tensile strength, making it suitable for applications that require strong stud bolts. The combination of strength and corrosion resistance is particularly valuable in industries such as oil and gas, petrochemical, and marine.


Temperature Resistance: Duplex Steel 31803 retains its mechanical properties at both low and high temperatures, which broadens its range of applications.


Weldability: It has good weldability, but care should be taken to use appropriate welding procedures to maintain its corrosion resistance. Post-weld heat treatment may also be necessary.
