The SS 317 Nuts are manufactured from stainless steel grade UNS S31700 / EN 1.4449, an austenitic alloy enriched with chromium, nickel, and molybdenum. This composition provides improved resistance to pitting and crevice corrosion, especially in environments containing chlorides and harsh chemicals. Because of its enhanced corrosion resistance compared with standard stainless steel grades, 317 Stainless Steel Nuts are commonly used in chemical equipment, pulp and paper processing, and industrial piping systems.
The SS 317L Nuts are the low-carbon version of grade 317, identified by UNS S31703 / EN 1.4438. The reduced carbon content helps improve weldability and reduces the risk of intergranular corrosion in welded structures. Due to these advantages, 317L Stainless Steel Nuts are widely used in applications involving welded assemblies, high-temperature equipment, and environments exposed to acidic chemicals. Variations such as SS 317L Hex Nuts, Stainless Steel 317L Lock Nuts, and UNS S31703 Heavy Hex Nuts are commonly used in industrial fastening systems that require both strength and corrosion resistance.
