Duplex Steel Stud Bolts possess a remarkable blend of strength and resilience, thanks to their nearly equal parts austenitic and ferritic microstructure. This unique composition grants them exceptional mechanical properties, offering a yield strength that is roughly double that of standard austenitic steels. They also exhibit outstanding toughness and excellent resistance to stress corrosion cracking, making them far more durable than many alternatives when facing challenging conditions.
