Stainless Steel 316L Fasteners are low-carbon molybdenum-bearing stainless steel fasteners identified by UNS S31603 and commonly associated with Werkstoff No. 1.4404. They offer excellent corrosion resistance, particularly against chlorides and many chemical environments, and are available as bolts, nuts, screws, threaded rods, stud bolts, and washers.
316L Stainless Steel Fasteners – Bolts, Nuts, Screws & Stud Bolts
Stainless Steel 316L Fasteners are corrosion-resistant fastening components manufactured from low-carbon austenitic stainless steel containing chromium, nickel , and molybdenum. The addition of molybdenum gives 316L better resistance to chlorides, pitting, and many chemical environments than conventional 304 stainless steel. These fasteners are widely used where reliable bolted connections, dimensional accuracy, and long-term resistance to corrosive service are required.
What Are Stainless Steel 316L Fasteners?
Stainless Steel 316L Fasteners are manufactured from SS 316L, an austenitic stainless steel grade with a maximum carbon content of approximately 0.03%. Its chromium-nickel-molybdenum composition provides a useful combination of corrosion resistance, toughness, formability, and weldability.
The lower carbon content of 316L helps reduce the risk of sensitization after welding, making the grade suitable for fabricated equipment and assemblies where welding and corrosion resistance are both important.
