Stainless Steel 317/317L Fasteners contain iron, chromium (18–20%), nickel (11–14%), and molybdenum (3–4%), providing better corrosion resistance than common stainless steel. The 317L grade, with minimal carbon content (≤0.03%), improves weldability and minimizes carbide precipitation, and hence is suitable for welded components. Mechanical properties consist of high tensile strength, good ductility, creep strength, and greater resistance to pitting and crevice corrosion. Such properties provide durability and reliability over a long period of time, even under severe chemical, marine, and high-temperature environments, making them effective for severe industrial fastening requirements.
Stainless Steel 317/317L Fasteners have diverse applications in highly corrosive and structurally strong industries. They are best suited for chemical processing equipment, petrochemical facilities, and pharmaceutical machinery exposed to aggressive chemicals or high heat. In marine environments, they resist chloride-induced corrosion, which makes them durable in seawater applications. These fasteners are also implemented in industrial structures, pipelines, pumps, and valves to ensure efficient assembly and durability under stringent conditions. Their mechanical strength, corrosion resistance, and low maintenance make 317/317L fasteners a necessity for critical systems in chemical, marine, and high-temperature industrial applications.
