Super Duplex
The term “Super Duplex” was first used in the 1980’s to denote highly alloyed, high-performance Duplex steel with a pitting resistance. With its high level of chromium, Super-Duplex steel provides outstanding resistance to acids, acid chlorides, caustic solutions and other environments in the chemical/petrochemical, pulp and paper industries, often replacing 300 series stainless steel, high nickel super-austenitic steels and nickel-based alloys. At Callstain we have worked very closely with organisations within the offshore oil and gas industry supporting companies in the Norwegian oil fields and are proud of our in depth knowledge of MDS Specifications.
- Excellent resistance to chloride stress-corrosion cracking
- High thermal conductivity
