The SS 317 Fasteners are manufactured from stainless steel grade UNS S31700 / EN 1.4449, an austenitic alloy containing chromium, nickel, and higher molybdenum content. This composition improves resistance to pitting, crevice corrosion, and chloride-based environments compared to many conventional stainless steel grades. Because of these properties, 317 Stainless Steel Fasteners are commonly used in aggressive industrial environments where both strength and corrosion resistance are essential.
The SS 317L Fasteners are the low-carbon version of grade 317, identified by UNS S31703 / EN 1.4438, which provides improved weldability and reduced risk of intergranular corrosion in welded structures. Due to these characteristics, 317L Stainless Steel Fasteners are frequently used in equipment exposed to acidic chemicals, high temperatures, and chloride environments. Common variations include SS 317L Bolts, Stainless Steel 317L Nuts, SS 317L Stud Bolts, and UNS S31703 Washers, making them suitable for a wide range of industrial fastening applications.
