Alloy 2507 Bolts and Hex Nut manufacturer in India
Fasteners are based on screws and screws holes. The screws have male threads and the holes have female threads. There are different materials used and different types produced. Duplex stainless steel is also used to manufacture fasteners. We are leading Super Duplex 2507 Bolts Manufacturer and we produce fasteners such as bolts, nuts, screws, studs and others as well.
Great Steel & Metals is in the business long enough and produce high quality SDSS Stainless Steel Nut to be used in different applications. The SDSS 2507 belongs to a family of super duplex stainless steel which is corrosion resistant, strong and is cost effective. The high corrosion resistant properties make the steel be used in fittings, heat exchangers, storage vessels, fans and wires. There are different types of Super Duplex 2507 Screws with different head pieces to suit the different tools and applications. The Super Duplex 2507 Flat Washer can withstand high temperatures and pressures so that it is used in hydraulic piping and in water heaters. Our super duplex products are highly corrosion resistant because of the 25% chromium and 4% molybdenum in the composition. This particular material grade also has 7% nickel which adds to the ductility and strength of the DIN 1.4410 Super Hex Bolts that are used with high strength applications. Our SAF 2507 Hex Cap Screw is easy to install and has excellent mechanical properties to be used with storage vessels, cargo tanks and other high end products. Please contact us for further product details and prices.
