Essentially a fastener, these components are threaded on both ends. These fasteners look like threaded rods. The use of Stainless Steel Stud Bolts is to screw into a fixture with the other end sporting a nut. Any Stainless Steel Stud Bolt Manufacturers In India recommends using these stud bolts for a permanent fix. For temporary joints, using an ordinary bolt serves the purpose. However, because the Double End Threaded Stud Bolts lacks its head, so to speak, it is very difficult to pull out.
Hence, these fasteners make a very good permanent solution. Although there are several alloys and metals that may be used to manufacture them, it is the Stud Bolts For Stainless Steel Flanges that come across as very durable and economical. Operations that cannot afford to have elevated costs generally use alloy 304. Unlike other alloys, Stainless Steel 304 Stud Bolts are available easily across all global markets, and they are cost efficient as well.
Since the alloying elements in Stainless Steel 304 Stud Bolts are lower than grade 316, the cost drastically reduces. However, the mechanical properties of this particular alloy are much lower than Stainless Steel 316 Stud Bolts. In addition to a higher content of alloying material, the inclusion of molybdenum in a significant degree tends to increase the mechanical as well as the corrosion resistance properties of grade 316 ASTM A193 SS Stud Bolts. Moreover, because it is a molybdenum containing alloy, the corrosion resistance of M16 Stainless Steel Stud Bolts is outstanding in marine environments.
