Super duplex stainless steel

Super Duplex stainless steel, offered by Icon Steel, represents a premium choice for industries that demand both strength and corrosion resistance. Combining the best features of both austenitic and ferritic stainless steels, our Super Duplex stainless steel provides superior performance in aggressive environments. It is particularly well-suited for applications in chemical processing, oil and gas exploration, and marine engineering, where its high resistance to pitting, crevice corrosion, and stress corrosion cracking can significantly extend the lifespan of equipment.

Key Features :

Even better resistance to pitting and crevice corrosion than duplex stainless steel.

Provides even higher tensile and yield strength than duplex.

Exceptional resistance to fatigue and stress-corrosion cracking.

Less prone to thermal expansion, which ensures dimensional stability.

Combines durability and strength, offering longer service life in extreme environments.
