Super duplex Stainless Steel is a highly alloyed , good performance
duplex steel with a pitting resistance . Super Duplex offers good
resistance to pitting and crevice corrosion . It is suited for use
in aggressive environments . It also has good resistance to stress
corrosion cracking in chloride and sour environments . And it has
good resistance to erosion corrosion and corrosion fatigue .
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 .
