Punit Fasteners, a top-notch manufacturer and supplier located in Delhi, India, specializes in high-quality Stainless Steel 314 Nuts that are perfect for extreme high-temperature applications. With a strong focus on quality, precision, and durability, the company ensures that its fasteners meet rigorous industrial and international standards. These SS 314 Nuts are crafted for outstanding oxidation resistance and structural integrity in environments that exceed 1000°C. They find their place in various industries, including metallurgy, furnaces, petrochemicals, and thermal processing, and come in a variety of sizes and thread specifications. Punit Fasteners also provides custom manufacturing to cater to specific project or industry needs.
Stainless Steel 314 Nuts are crafted from a high-temperature austenitic stainless steel alloy, featuring around 24–26% chromium and 19–22% nickel, with added silicon for enhanced oxidation resistance. These nuts maintain impressive tensile strength (typically between 550–700 MPa) even at elevated temperatures up to 1150°C (2100°F). While they may not be the best choice for wet or acidic environments, SS 314 shines in dry, oxidizing conditions. The material is non-magnetic when annealed and boasts excellent thermal stability, low creep, and resistance to scaling—making it a great fit for critical bolted joints that face prolonged heat and thermal cycling.
