Punit Fasteners, a reputable name in the precision fastener manufacturing scene in Delhi, India, specializes in high-quality Stainless Steel 316L Fasteners. These fasteners are celebrated for their exceptional corrosion resistance, weldability, and strength. SS 316L, being the low-carbon version of 316 stainless steel, is perfect for critical applications in environments that are either highly corrosive or require strict hygiene. You’ll find these fasteners in various industries, including marine, chemical processing, pharmaceuticals, food & beverage, and wastewater treatment. Crafted under rigorous quality control standards, Punit Fasteners offers 316L fasteners in a range of forms—like bolts, nuts, washers, and screws—available in different sizes and finishes to meet global industry standards.
Stainless Steel 316L Fasteners are made up of 16–18% chromium, 10–14% nickel, 2–3% molybdenum, and ≤0.03% carbon. The lower carbon content helps prevent sensitization during welding, which boosts resistance to intergranular corrosion. Molybdenum enhances resistance to pitting and crevice corrosion, especially in environments rich in chlorides. These fasteners boast a tensile strength of 485–620 MPa and a yield strength of 170–300 MPa, all while maintaining excellent ductility, toughness, and non-magnetic properties when annealed. Their outstanding corrosion resistance, formability, and thermal stability make them perfect for both structural and sanitary fastening needs across demanding industries.
