Punit Fasteners is a reliable manufacturer and supplier of Stainless Steel 316H Fasteners based in Delhi, India. We pride ourselves on delivering top-notch fastening solutions that are specifically designed to withstand high temperatures and corrosive environments. The SS 316H grade is a high-carbon variant of the standard 316, crafted to provide superior strength and creep resistance when the heat is on. Our selection of 316H Fasteners includes everything from bolts and nuts to washers, screws, studs, and threaded rods, all made to meet international standards and perfect for critical applications in refineries, power plants, chemical processing, and marine settings.
Stainless Steel 316H is composed of 16–18% chromium, 10–14% nickel, and 2–3% molybdenum, along with a higher carbon content (≥0.04%). This boost in carbon enhances its strength at high temperatures and improves long-term creep resistance. These fasteners are known for their exceptional resistance to corrosion, particularly in environments rich in chlorides and acids. Typically, SS 316H Fasteners boast a tensile strength exceeding 515 MPa and maintain their mechanical integrity even under high-pressure and high-temperature conditions.
