Stainless Steel 317L Fasteners
Sankalp Alloys Overseas is one of the reputed manufacturers, suppliers, stockists, and exporters of high-quality Stainless Steel 317L Fasteners. The fasteners are designed by an austenitic chromium-nickel-molybdenum alloy that gives it excellent corrosion resistance properties and superior mechanical properties. Since this contains a low carbon content, Stainless Steel 317L Fasteners offer very nice resistance to sensitization and intergranular corrosion, which makes them perfect for all types of applications where demand is prominent.
Our stainless steel 317L fasteners are designed for the harshest environments and for protection against corrosion in all forms of aggressive media. This means operation is also suitable in seawater with high chloride content and in industrial environments where various chemicals are present. The addition of molybdenum in the alloy increases its resistance to pitting and crevice corrosion; hence, making these fasteners suitable for use in marine engineering, chemical processing, and the petrochemical industry where the concentration of such corrosive elements is relatively high.
The mechanical properties of Stainless Steel 317L Fasteners are no less impressive; high tensile and yield strength provides durability and reliability for longevity in applications that have requirements that necessitate robust fastening solutions. Used at higher temperatures, the fasteners do not lose their structural integrity and can thus find application in heat exchangers, boilers, and other high-temperature equipment. Low carbon content improves weldability, allowing smooth and secure welds without the risk of carbide precipitation.
Sankalp Alloys Overseas specializes in an exhaustive portfolio of Stainless Steel 317L Fasteners that include bolts, nuts, screws, washers, and threaded rods. The quality of the product is always checked against the specified quality standard and specifications, like ASTM and ASME. This provides uniform performance and reliability for the products. We offer fasteners in multiple sizes and dimensions based on requirement in different industries or applications.
