Stainless Steel 316L Fasteners

Stainless Steel 316L Fasteners are known for their widely used characteristics, which include high tensile strength and excellent wear resistance in high-temperature service conditions. Sankalp Alloys Overseas is a manufacturers, suppliers, stockists, and exporter of high-quality 316L Stainless Steel Bolts, Screws, Nuts, and all types of fasteners available in different specifications and types. As such, it remains that the chief difference among these two grades is that compared to 316, the content of carbon found in grade 316L is lower; hence, the former would have high ductility without the loss of strength as compared to the latter.

One of the key features of UNS S31603 Bolts is their excellent corrosion resistance, making them quite suitable for use in seawater, marine, and brackish water applications. Due to this property against chloride-ion corrosion cracking, these fasteners find extensive usage in saltwater desalination plants, marine constructions, and sea-based operations. In addition to this, the lower carbide precipitation of grade 316L in the welding process adds to its weldability—that is, making it easier and more reliable to weld.

Sankalp Alloys Overseas also deals in 316L Stainless Steel Threaded Inserts, which are used for applications wherein the bolt heads or nuts cannot be used. Fasteners include 316L Stainless Steel Stud Bolts available in all sizes to fit different application requirements, conforming to different grades and standards. We also keep stocks in a huge array of fasteners, including—but not limited to—316L Stainless Steel Threaded Rods and Washers. Feel free to reach out to us for more detailed information regarding our product range, pricing, and full catalog.

Sankalp Alloys Overseas is an important name in the industry for offering quality ventilated 316L Stainless Steel Fasteners. We also adhere to a stringent quality control that independently checks products at every production stage to match global standards of quality and performance. Its excellent corrosion resistance properties and strength in service under high-temperature and aggressive conditions make our fasteners well applicable in seawater and also in other media, which are corrosive and demanding.

High chromium and high molybdenum content of our 316L Stainless Steel Fasteners increase the overall corrosion resistance of the fitting compared to any other cast stainless steel. Good weldability of our SS UNS S31600 Fasteners does not allow carbide precipitation to happen due to the welding process. It gives a high tensile strength to the welds. These features attribute to making our ASTM A193 SS 316 Fasteners one of the most sought-after marine grade stainless steel fittings.
