These stud bolts are made from austenitic ferritic stainless steel, specifically designed to provide higher strength and corrosion resistance. These Duplex Stainless Steel 2205 Stud Bolts are significantly upgraded version of the 300 series stainless steel stud bolts. They possess good general corrosion reistance properties along with a high resistance to chloride stress corrosion cracking, pitting and crevice corrosion. They also exhibit high strength and good fatigue resistance. The fatigue limit/yield strength is twice as high in comparison to 300 series stainless steel. They are known for their high energy absorption and low thermal expansion properties. Their typical use would be in the -50°C to 300°C temperature range where its properties are put to the best use.
The presence of chromium, molybdenum and nitrogen also make sure they are protected against chloride environments. This property is highly needed and is useful for marine industries, bleaching operati
