Super duplex stainless such as duplex is a mixed microstructure of austenite and ferrite which has improved strength over ferritic and austenitic steel grades . The main difference is super duplex has a higher molybdenum and chromium content which gives the material greater corrosion resistance . Super duplex has the same benefits as its counterpart - it has lower production costs when compared with similar ferritic and austenitic grades and due to the materials increased tensile and yield strength , in many cases this gives the purchaser the welcomed option of purchasing smaller thicknesses without the need to compromise on quality and performance .

Features :

1 . Outstanding resistance to pitting and crevice corrosion in seawater and other chloride containing environments, with critical pitting temperature exceeding 50°C
2 . Excellent ductility and impact strength at both ambient and sub-zero temperatures
3 . High resistance to abrasion, erosion and cavitation erosion
4 . Excellent resistance to stress corrosion cracking in chloride containing environments
5 . ASME approval for pressure vessel application
