Duplex Steel 2205 fasteners are a type of high-strength, corrosion resistant stainless steel components that are very popular among manufacturers of highly corrosive environment equipment. These parts find their applications in oil and gas industries, marine, chemical processing and desalination industries where standard stainless steel like 316L fail to perform effectively. Duplex steel fasteners 2205 offer superior resistance to stress corrosion cracking, pitting and crevice corrosion in chloride rich environments. A typical example, the oil and gas industry can be a breeding ground for corrosion due to exposure to harsh chemicals such as hydrogen sulfide, carbon dioxide and chlorides. Therefore, Duplex steel 2205 Fasteners have been identified as the perfect choice of material for offshore drilling rigs, pipelines and chemical storage tanks due to their excellent corrosion resistance. Besides having longer service life and being less maintenance intensive, they also minimize downtime and raise productivity. In addition, they perform excellently in harsh environments including offshore drilling rigs, pipelines and chemical storage tanks.

Super Duplex 2507 Fasteners are made from a stainless steel alloy containing 25% chromium, 4% molybdenum and 7% nickel, Super Duplex 2507 fasteners (EN 1.4410) is a perfect combination of composition and properties. Super Duplex screws produce both highest strength and excellent localized corrosion resistance to chlorides. This metal finds its application widely for its yield strength which is twice that of annealed austenitic stainless steels, like 304 and 316 stainless. Resistance to chloride corrosion is one of the main features of Super Duplex 2507 screws due to the composition of this specialty metal. The high molybdenum, chromium and nitrogen levels of Super Duplex makes these fasteners perform very well against chloride corrosion like pitting and crevice attacks and their ferritic structure renders them resistant to stress corrosion cracking in warm chloride environments. Super Duplex 2507 fasteners are known to deliver uniform corrosion protection even from organic acids such as formic and acetic acid in addition to inorganic acids especially those containing chlorides. Visionalloys is a well-known entity in the market of production and exportation of Super Duplex 2507 Fasteners in USA, Jordan, UK etc.
