Duplex stainless steel UNS S31803 fasteners are double-phased Ferritic, 3% molybdenum, austenitic 22% chromium along with 5 to 6% of stainless steel that is alloyed with Nickel. It is one of the most widely utilized graded steel which shows amazing strength characteristics. The specifications of Duplex stainless steel UNS S31803 Fasteners are double of the basic grades of stainless steel. These types of stainless steel also show a very good strength of fatigue. Not only this they have also outstanding resistance to counter cracking of stress corrosion, crevice, pitting, erosion along with general corrosion in general working conditions and extreme environments.
They can be used in the different types of chemical processing, storage and transport as they can handle the workability in pressure vessels, pipes, and tanks along with heat exchangers. Their properties remain unaltered in different chloride and marine environments. They have high contents of chromium, nitrogen along wit
