Stainless Steel 317 Stud Bolts, UNS S31703 Stud Bolts, 317L Stainless Steel Stud, SS 317L Tap End Stud Bolt, SS 317 Double End Threaded Stud, 317 SS Half Threaded Stud Bolts, SS 317L Tie Rods, SS 317 Stud Bolts Manufacturer.
Extra molybdenum is added to austenitic grade UNS S31700 (EN 1.4449) to give SS 317 stud bolts superior resistance to pitting and crevice attack. As a stainless steel 317 stud bolts supplier and manufacturer, we provide these fasteners for chemical processing units, pulp and paper plants and piping systems with aggressive materials. Tensile strength remains unaffected in chloride-rich conditions.
The lower carbon, UNS S31703 (EN 1.4438), of SS 317L reduces the risk of intergranular corrosion at welds. There is an improvement in weldability that is significant over the standard 317. This makes us a good stainless steel 317L stud bolts manufacturer and supplier for high-temperature use and welded assemblies where the integrity of the seams is most crucial.
Stock consists of stainless steel 317L double end stud bolts, 317L tap end and stainless steel 317L threaded stud bolts in a variety of diameters and lengths. They are used every day, to ensure secure, leak-free joints without loss of pressure in flange connections, valve assemblies and pressure vessels throughout the petrochemical industry and in the marine industry.
