Bright Annealed Surface 32750/32760 Duplex Steel Tube Straight Length Cold Rolled Tube

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 .
