Harsh Metalloys, a well-respected manufacturer and supplier located in Mumbai, India, specializes in top-notch Stainless Steel 321 Flanges that are perfect for high-temperature and corrosive environments. SS 321 is a titanium-stabilized austenitic stainless steel known for its remarkable resistance to intergranular corrosion and oxidation, particularly in situations with frequent temperature changes. These flanges are crafted to meet international standards like ASTM A182 and come in various types, including weld neck, slip-on, blind, socket weld, and threaded options. They are ideal for piping systems in power plants, refineries, and chemical industries, ensuring reliable performance even under extreme conditions.
Stainless Steel 321 Flanges are made up of 17–19% Chromium, 9–12% Nickel, and Titanium for stabilization (at least five times the carbon content) to avoid carbide precipitation during welding. These flanges boast a tensile strength ranging from 515 to 750 MPa and a yield strength of about 205 MPa. They perform exceptionally well at elevated temperatures, reaching up to 870°C (1600°F), and offer good creep resistance and stress rupture strength. SS 321 maintains its structural integrity in oxidizing environments and is non-magnetic when annealed. Its excellent weldability and corrosion resistance make it a great choice for critical flanged connections.
