Kencotube is manufacturer & trader for high quality Super Duplex Steel Fasteners, which have a body-centered cubic crystal system and contain between 10.5% and 27% chromium with very little nickel. Due to high contents of chromium, nickel, molybdenum and nitrogen, corrosion resistance of Super Duplex Stainless Steel Fasteners and in some cases mechanical properties are superior to conventional Cr-Ni and Cr-Ni-Mo grades. The resistance to uniform corrosion and localized corrosion in Duplex Steel Fasteners, including chloride and sulphide induced stress corrosion cracking, is very good. Super Duplex Steel Nuts contains chromium (12–14%), molybdenum (0.2–1%), nickel (below 2%), and carbon (around 0.1–1%), where providing it more rigidity but making the product a bit more hard. Super Duplex Steel Bolts is quenched and magnetic, and can be degraded by the presence of chromium, an intermetallic phase which can precipitate upon welding.
Super Duplex Steel Stud Bolts is a contemporary trend for roofing product for airports owing to its low shine reflectance to retain pilots from blinded, as well for its features that permit thermal reflectance so as topreserve the surface of the roof nearly ambient temp. Despite its design and use, Super Duplex Steel Screws can still be susceptible to corrosion, and especially in corrosive environments. Challenging environments in Super Duplex Steel Washers include saline environments, such as coastal areas where regular exposure to sea salt is common and areas where de-icing salts are common during winter.
